I. INTRODUCTION
CalDB 4.6.4 is an upgrade to the Chandra CalDB, which includes the following items:
- ACIS GRADE file for CC33_GRADED case
II. SUMMARY OF CHANGES
A. ACIS GRADE file for CC33_GRADED case
| Location: | $CALDB/data/chandra/grade/ |
| Filename: | acisD2009-11-01gradeN0005.fits |
A change in the ACIS parameter block control file effective 2009-11-01T00:00:00 results in the ACIS FLT GRADE "66" events being telemetered for the CC-mode case. These events had never been telemetered for CC-mode cases before that date. A modification has been made to the mapping of Flight Grade 66 events for the GRADE CC-modes, wherein these events are to be assigned ASCA GRADE "2". As such, these events will not be removed from the level 2 event list thereby generated. The new GRADE file above is the means whereby the new mapping is being done in SDP, and in a later release of CIAO (v4.7).
PIPELINES/TOOLS AFFECTED:
