Introduction
Summary of Activities
During the past 12 months the DWP PI team has continued to process, validate, and deliver data products to CAA.
The delivery of data has proceeded almost to schedule.
CORR datasets slightly behind availability of FGM 5VPS and AUX data. These are now available until March/February Production of remaining CORR datasets for 2013 should by completed by end August as in proposed schedule.
Reprocessing of CORR data sets due to FGM updates.

5. Status of Software Development
All software required to generate the current set of DWP datasets already exists. These applications have been running for several years.
Following the problems with our UNIX RAID system production is now being ported to new MAC platform.
LOG, COR completed, caveats partly complete
UT_PIOR relies on commanding data – still Unix based
CORR is still based on Linux hardware

6. Calibration/Cross-calibration
DWP data sets do not require any in orbit calibrations.
DWP does not take part in any cross calibration activities.

11. Recommendations from OR8
OR8-R13
The board recommends that instrument teams ensure that all ancillary datasets are fully described in their ICDs.
DWP Response
All DWP datasets are fully described in the ICD.
OR8-R14
All instrument teams should ensure that their user guides contain a detailed description and time-line of instrument operations and failures.
Most of this information is already contained within the UG.
OR8-R15
The board recommends that all teams investigate data quality at mode changes and instrument switch-on or switch-off.
We are currently looking into this aspect of operations.

Action Items
CC18-AI-13
to use a file listing flag in command line to get a listing of active files on the CAA
DWP response
DWP already checks for the availability of new FGM 5VPS and AUX files as they are required for production of the CORR data sets.
CC19-AI-01
check that the headers are complete and correct. This concerns particularly various descriptions in different levels (experiment, instrument, dataset).
The experiment/instrument/data set descriptions in the header files have been updated.
CC19-AI-04
to reprocess the pitch-angle products for the reprocessed FGM dates (for list, see slide 7 of annex 7).
All data periods have now been reprocessed and delivered to CAA

13. CAA 9th Operations Review, ESAC
Action Items
CC19-AI-17
to deliver the annual report and ICD on the Double Star datasets for the OR-9 review.
DWP response
Done.
CC19-AI-18
to deliver the Double Star datasets of to the CAA.
The summary plots from LPP are ready for delivery. Pipeline for power spectra data is in place. Code for correlator products is being ported and test on MAC.
