"Suggested Changes to the RSDP Pipeline for FOC Data"

By: P. Greenfield

Abstract excerpted from the report:

The RSDP pipeline currently has deficiencies with regard to how exposures
are flat fielded. This report outlines the problems with the current
order of processing which has flat fielding done before geometric 
correction, and recommends that the order of the processing steps be
reversed. Data are presented showing the size of the effects on the
calibration of FOC data. Recommendations are also made for changes to the
pipeline to make useful the data quality mask produced for every exposure,
which currently contains no useful information.
