1 CCF Components
Name of CCF VALDATE EVALDATE Blocks Changed XSCS Flag
EPN ADUCONV 0139.CCF 2007­08­16T22:36:18 OFFSET GAIN NO
2 Changes
A new PN Bad Pixel Table is systematically in use from revolution 1408 onwards, and the BPT CODE
header keyword value has been updated accordingly.
The BPT CODE keyword identifies the current version of both the uploaded bad pixels and
the column o#sets and allows cross­checking between HK telemetry and CCF issue. Although the
uploaded o#sets remain unchanged, for consistency the EPN ADUCONV CCFs do require an update
because of the new the BPT CODE keyword value in the OFFSET GAIN extension.
3 Scientific Impact and Estimated Scientific Quality
There are no scientifically relevant changes with respect to the previous CCFs. The changes in the
new CCF have no scientific impact whatsoever.
4 Test Procedures and Results
Validity date verified with cifbuild; correct functionality tested with epproc (SAS 7.1).
