Examples of problems found and the solutions implemented 8

9 Problem Type 1 –missing Raw 3DF data PITCH_SPIN data RPAD missing!? IDFS DS 3DF data IDFS DS_rp 3DF data No plot As there is no ‘G’ version raw data Regenerated 3DF=>RPAD=>PITCH_SPIN PITCH_SPIN data DAA Format Data DAA data FIXED by repeating Step 5,6 (Checking, PITCH_SPIN Regeneration) PITCH_SPIN data ‘O’ version PITCH_SPIN data ‘G’ version PITCH_SPIN Merged data Spin Origin

Problem Type 2 –incomplete IDFS 3DF data IDFS DS 3DF data IDFS DS_rp 3DF data PITCH_SPIN data DS IDFS 3DF data is complete, hence DS IDFS RPAD and DAA PITCH_SPIN are complete. DS_rp IDFS 3DF is not complete, hence DS_rp IDFS RPAD and DAA PITCH_SPIN are not complete (checked by doing Step 2) However, as far as the DAA cef file is concerned our codes allow the filling of missing spins, so that we deliver the complete dataset 10 DAA Format Data No FIX required (checking of data plots (Step 5) to confirm completeness of data & Step 2) PITCH_SPIN data ‘O’ version PITCH_SPIN data ‘G’ version PITCH_SPIN Merged data Spin Origin

Problem Type 3 –missing DS or DS_rp IDFS RPAD data PITCH_SPIN data 11 IDFS DS 3DF data IDFS DS_rp 3DF data DAA Format Data DAA data FIXED by Regeneration, Step 6

Problem Type 4 –no IDFS 3DF data (e.g. data gap/PEA OFF/raw files, but no data) Solution: generate FILL file 12 DAA Format Data IDFS DS 3DF data IDFS DS_rp 3DF data DAA data can NOT be FIXED as there is no data due to PEACE being turned OFF or due to data gaps

Problem Type 5 –shifted spins due to corrupt data stream 13 PITCH_SPIN data IDFS DS 3DF data IDFS DS_rp 3DF data PITCH_SPIN data 13 Regenerated PITCH_SPIN DAA Format Data DAA data FIXED by removing shifted spins, Step 4

Problem Type 5 Example: 5min zoomed plot of shifted spins 14 DAA Format Data The subroutine in the merging code: peaceDAAmerge.pl, removes shifted spins if they occur in the original ‘O’ or the reprocessed ‘G’ version Double Star data set (Step 4). The updated code has been tested on intervals when we have various problems in ‘O’ and/or ‘G’ data sets as shown in the example on the LHS. The best spins, from ‘O’ and ‘G’ data are taken minus the shifted spins, which results in the ‘M’ version as shown in the third panel plot. PITCH_SPIN data ‘O’ version PITCH_SPIN data ‘G’ version PITCH_SPIN Merged data Spin Origin DAA data FIXED by removing shifted spins using Step 4

Although, IDFS 3DF data looks fine we had strange PITCH_SPIN data plots, with data missing below ~700 eV as in these cases the RPAD code was missing the start or end timestamp due to a corrupt data stream (top LHS plot) We have produced v2 (Step 3) of the DS/DS_rp RPAD generation code that fixes this problem (see bottom LHS plot) Problem Type 6 –no data below ~700eV in DAA PITCH_SPIN IDFS DS_rp 3DF data PITCH_SPIN data IDFS DS 3DF data PITCH_SPIN data 15 Regenerated RPAD => PITCH_SPIN DAA Format Data DAA data FIXED by repeating Step 3 with v2 RPAD code

Problem Type 7 –corrupt or empty IDFS DFUNIT FGM data TC-1 These dates had corrupt IDFS DFUNIT FGM data in our system at MSSL: , , , , , Solved by regenerating IDFS DFUNIT and IDFS RPAD and Merged DAA files TC-1 The dates on the next slide had empty RAW FGM data in our system at MSSL. (see next slide) 16 Type-7 corruption problem FIXED by repeating Step 1, Step 3, Step4 Type-7 empty raw FGM file problem means we CANNOT FIX IDFS DFUNIT data in order to make IDFS RPAD files and subsequently DAA PITCH_SPIN

New codes were designed to use new DAA cleaned FGM data, but we are waiting for clarification of the coordinate system of the new data) Mullard Space Science Laboratory 20

NOTE: We were able in the past to fix the “ab” sweep preset correctly in ~99% of the cases as we knew that the high (H) energy preset had a smaller energy range coverage compared to the low (L) energy sweep BUT in the ‘aa’ sweep preset the high (H) and low (L) energy sweeps have the same energy coverage, hence we fixed ~95% of the cases by recognising which spins were even or odd to assign the correct preset value. Definition of ‘aa’ sweep preset on Double Star The “aa” mode is used between: 2004/Aug/17-29, 2004/Nov/01-07 on TC-2 –Double Star: HEEA (for TC-1), LEEA (for TC-2) –Use“TL1L2B” for alternating sweep preset in peacemoments B T overlap aa ab Energy Time In “aa” preset mode the overlap (dashed box) from the high (H) and low (L) energy sweep is transmitted in telemetry In “ab” preset mode the overlap (black box) from the high (H) and low (L) energy sweep is NOT transmitted Mullard Space Science Laboratory High (H) sweep preset energy range Low (L) sweep preset energy range

Mullard Space Science Laboratory Examples of more difficult ‘aa’ sweep preset cases and solutions found when only a partial fix was possible (the remaining 5% of ‘aa’ cases) 25

(233) In this case the DAA production code can be adjusted to make a good DAA CEF file The recipe file that the DAA code makes ensures that in this case spins only from fixed DS data is used to make final DAA file (here version ‘M’) Mullard Space Science Laboratory 26 PITCH_SPIN data ‘O’ version (low and high energy sweep preset FIXED 100%) PITCH_SPIN data ‘G’ version (only low energy sweep could be FIXED 100%) PITCH_SPIN Merged data (The merged data set is 100% FIXED) Spin Origin DAA Format Data

(234) In this case only the DS high energy sweep is ok (see panel 1) and only the low energy sweep from DS_rp is ok (see panel 2) The DAA production code can be adjusted to take only : DS: high energy sweep from panel 1 and DS_rp: low energy sweep from panel 2 to make the final DAA file shown in panel 3 Hence data from alternate files is taken as shown in panel 4 Mullard Space Science Laboratory 27 DAA Format Data PITCH_SPIN data ‘O’ version (only HIGH energy sweep could be FIXED 100%) PITCH_SPIN data ‘G’ version (only LOW energy sweep could be FIXED 100%) PITCH_SPIN Merged data (The merged data set is 100% FIXED) Spin Origin

(241) In this case only the DS data is used to make the correct DAA CEF for a case when there are data gaps.

Current Status 32

DAA Current Status Delivered to DAA: 3DX TC-1 test files: Nov-Dec 2004, but not TC-2 Not Delivered yet to DAA: PITCH_SPIN: (made using DS and DS_rp IDFS RPAD data based on current IDFS DFUNIT data) Validation/Fixing Problems TC-1 => – 98% Finished (still some Type-6 problems remaining in 2007 only) TC-2 => –Finished 100%, –Not started yet DFUNIT: MSSL has IDFS DFUNIT data files, but not the Full Resolution DAA FGM files yet to test Mullard Space Science Laboratory 33

DAA Future Production Plan To be delivered to DAA: We could start delivering DAA PITCH_SPIN for earlier years now, after PI check’s DAA MOMENTS could be made and delivered without checks being performed –NOTE: It is not always possible to determine the spacecraft potential reliably from PEACE data, which is a pre-requisite for good MOMENTS (see next two example slides for reasons) DAA 3DX production may be put on hold in order to focus on Cluster related work Mullard Space Science Laboratory 34

Estimating spacecraft potential from PEACE data (good case) 35 In this case we have a clear distinction between the photo-electron and plasma electron populations, which allows the s/c potential (black line) to be estimated from PEACE data. - In this case good MOMENTS can be produced. Plasma electrons Photo electrons s/c potential estimate TC1 ( ) 3DF 05:00-06:00 Mullard Space Science Laboratory

Estimating spacecraft potential from PEACE data (bad case) 36 In this case there is only the plasma electron population, but no photo-electron population (as dictated by instrument commanding in the past to protect the instrument from high photo-electron fluxes). - Hence, no s/c potential estimate can be made from PEACE data. -In this case good MOMENTS can NOT be produced, but trends could be useful.

Future Work Mullard Space Science Laboratory

DAA Future Work TC-1 &/or TC-2: 1.Deliver DAA PITCH_SPIN dataset in all units and spacecraft 2.Design/test DAA caveat software 3.Provide Double Star User Guide 4.Produce, validate, deliver DAA 3DX dataset in all units and spacecraft 5.Develop validation software for DAA MOMENTS 6.Provide improved spacecraft potential estimates where possible 7.Produce, validate, deliver DAA MOMENTS dataset 8.Following deliveries of these products, return to e.g. secondary code products (3DR, PAD) if resources allow 9.Provide Double Star Status Flags and documentation 10.Revisit calibrations for TC-1 and TC-2? 11.Corrections/testing new IDFS DFUNIT production code on Full Resolution (FR) DAA FGM data Mullard Space Science Laboratory 38

Summary –Main points DS/DS_rp IDFS RPAD re-generation is finished and problems were fixed (IDFS 3DF problems were also fixed in the process where necessary) Generation of DAA PITCH_SPIN data is finished for TC1/2 for all units/years Checking/Validating/Fixing/Regenerating of DAA PITCH_SPIN files –TC-1: 98% finished for all units/years (some Type-6 problems left in 2007 only) –TC-2: 100% finished for all units/ between –TC-2: Not yet started The delivery of TC-2 DAA PITCH_SPIN CEF files can start soon after PI check’s The merging software ensures that only the best DAA PITCH_SPIN data per/spin are used from the original (‘O’ version) OR reprocessed (‘G’ version) IDFS RPAD data to make the best final DAA CEF file possible (this also now includes the new module that removes shifted spins, which works in ~99% of the cases) Production of other products (e.g. DAA: 3DX, MOMENTS) may be put on hold as the team wishes to put priority on Cluster II related activities and partly due to a reduction in the PEACE operations team staffing (i.e. Yulia Bogdanova and Iryna Rozum have left the team) To fix all types of problems (including the regeneration of support data and problem dates, but excluding any calibration effort) for TC1/TC-2 has so far taken > 12 months and is not finished yet, which contributed to the delay of delivering the DAA data. 39 Mullard Space Science Laboratory
