1. 5 th SECCHI Consortium Meeting Orsay, France March 5-8, 2007 SECCHI Planning and Scheduling Ed Esfandiari NRL/Interferometrics, Inc.

2. Planning and Scheduling Overview Scientist Has Observing Plan Idea Scientist Creates Detailed Plan Plan is E-Mailed to SECCHI Planner Plan Gets Converted to an Observing Schedule Schedule Gets Uploaded to SECCHI

3. Creating an Observing Plan ● Detail is essential! ● User needs to be aware of the various processing tables http://stereo.nrl.navy.mil/planning_tool/orsay/pt_image_taking_commands.html http://stereo.nrl.navy.mil/planning_tool/orsay/pt_image_taking_commands.html  Image category (Normal, Dark, Sequence, etc.)  Image Parameters http://stereo.nrl.navy.mil/planning_tool/orsay/pt_tables.html http://stereo.nrl.navy.mil/planning_tool/orsay/pt_tables.html ● Camera setup (7 entires per instrument) ● Exposure (7 entires per instrument) ● Image processing (100 entries for all instruments) ● ROI and Occulter Mask (1 of each per instrument) ● Be aware of telemetry constraints ● Be aware of instrument constraints ● All full-res images will be 2176x2048 ● Indicate if SC-A and SC-B images should be synced

4. Other Information... ● Tables can be obtained from the SECCHI wiki page under “Planning”  http://secchi.nrl.navy.mil/wiki http://secchi.nrl.navy.mil/wiki ● Observing plans should be submitted several days in advance ● Plans should be sent to the SECCHI Operations Scientist (Simon Plunkett)

5. Scheduling ● Observing plans, once approved, are entered into the IDL- based planning tool by the SECCHI planner (Ed Esfandiari) ● Planning tool is “ a set of IDL routines (of LASCO/EIT heritage) that generates daily-weekly command files and/or synoptic programs for commanding the 3 SCIP and 2 HI telescopes. It is a GUI tool that takes advantage of all available telescopes and on-board resources to maximize the use of the telemetry downlink. ” ● Planning tool monitors image sequences, buffer sizes, partition (SSR1, SSR2) sizes, downlink rates, etc

6. Typical Scheduling Steps ● Observing plan is scheduled through a series of IDL widgets ● Either a new observing sequence is created or an old existing sequence is imported. ● Reusing observing plans can save a great deal of time!

7. Verifying the Plan ● An “OS Num” (Observing Sequence Number) is generated for each unique observation ● Once all OS's are complete, the schedule is verified ● Schedule conflicts produce a warning

8. Schedule successfully created!

9. Summary ● Plan your observations carefully and be as detailed as you can ● If at all possible, use the table entry numbers ● Be aware of telemetry, buffer and instrument restrictions ● Try to reuse old observing plans ● Allow plenty of time ● Make use of the planning resources on the SECCHI wiki page

10. Jan-Feb 2007 Schedules ● Over 100 calibration, first light and commissioning schedules ● First draft of operations synoptics  Synced COR and HI observations  Different SC-A and SC-B EUVI observations

11. Operations Synoptics-First Draft  Synced COR and HI images  SC-A http://stereo.nrl.navy.mil/planning_tool/orsay/schedule_operations_A.png http://stereo.nrl.navy.mil/planning_tool/orsay/schedule_operations_A.png ● 5487 images (1442 EUVI, 861 COR1, 194 COR2, 1189 HI-1, 1801 HI-2) ● NRL EUVI version – less images, longer exposures ● 52KB upload file size (1157 commands)  SC-B (pushing the limits) http://stereo.nrl.navy.mil/planning_tool/orsay/schedule_operations_B.png http://stereo.nrl.navy.mil/planning_tool/orsay/schedule_operations_B.png ● 7476 images (3431 EUVI, same COR and HI images as SC-A) ● Lockheed EUVI version – more images, shorter exposures ● 98KB upload file size (2572 commands)

12. Required Details ● EUVI  Normal ● SC, FW, WL, FPS, IPT, ExpT, CamT  Double ● SC, FW, WL, WL, FPS, IPT, ExpT, CamT  Dark ● SC, FPS, IPT, CamT, ExpTime ( 0:99998ms )  LED ● SC, FW, WL, FPS, IPT, CamT, Pulse ( 1-3300000 ), Color  Continuous ● SC, FW, WL, FPS, IPT, CamT  Sequence (n=2-4) ● SC, FW, WL*n, FPS, IPT, ExpT, CamT, Cadence ( 0=close-as-possible)

13. Required Details ● COR1 ad COR2  Normal ● SC, Polar, IPT, ExpT, CamT  Double ● SC, Polar, Polar, IPT, ExpT, CamT  Dark ● SC, IPT, CamT, ExpTime ( 0:99998ms )  LED ● SC, Polar, IPT, CamT, Pulse ( 1-3300000 ), Color  Continuous ● SC, Polar, IPT, CamT  Sequence (n=2-4) ● SC, Polar*n, IPT, ExpT, CamT, Cadence ( 0=close-as-possible)

14. Required Details ● HI-1 and HI-2  Normal ● SC, IPT, ExpT, CamT  Dark ● SC, IPT, CamT, ExpTime ( 0:99998ms )  LED ● SC, IPT, CamT, Pulse ( 1-4300000 ), Color  Continuous ● SC, IPT, CamT  Sequence (n=2-99) ● SC, IPT, ExpT, CamT, Cadence ( 0=close-as-possible)

15. An Example ● Scientist requests Full field EUVI images on SC-A every 2-hrs S1 FilterWheel, 284A, 1 sec exposure ● SECCHI planner requires SC-A, EUVI, Normal, FW=S1, Wave=284, FPS=Off, IPT=0, ExpT=6, CamT=1, Cadence=120min Where... ● IPTbl 0 >> SSR1, Rice Compressed ● EXPTbl 6 >> 1.0 Second exposure ● CamTbl 1 >> 2176x2048, no CCD summing, Hi gain
