Index Files, Versioning, Archiving
There shall be one .indx file per instrument. The names of the index files shall be caldbNnnnn.indx, where nnnn is a version number. In addition, there shall be a caldb.indx symbolic link to the most recent caldbNnnnn.indx (i.e., the one with the highest nnnn).
Every time a new ARD that is a CALDB member is ingested, new index files are created with the next higher version number and the symbolic links are moved, but no index files are deleted. The symbolic links ensure that by default the most recent version is used. The retention of previous versions of the index files not only allow access to those previous versions of the CALDB members but also ensure consistency between the various CALDB members.
All CALDB members will be identified by the CONTENT keyword in the header of their principal HDUs, which value will begin with "CDB_<instrument>_". The metadata kept on each file will include the values of the principal extension's CONTENT and CVSDnnnn keywords.

Structure changes as of 2000-01-05: hrma, letg, and hetg calibration files are now subsumed under the "tel" instrument specification. All of those files are to be indexed at the tel/index level, in the same file. The pcad directory has been added as of this date as well, including the nine subdirectories under bcf corresponding to each CCNM spec.
Filenames (2000/01/24):
All filenames are now set by this prescription. There is no uncertainty about this. If new conventions must be added, they will be.
General filename structure: <detnam>D<yyyy-mm-dd><ccnm>N<version>.fits
Exceptions:
-
DETNAM absent or 'NONE': Use INSTRUME value: <instrument>D<yyyy-mm-dd><ccnm>N<version>.fits
-
DETNAM = 'GRATING' (Keyword GRATING must be set = HETG or LETG): <grating>[<grattype><order>]D<yyyy-mm-dd><ccnm>N<version>.fits
-
Detector-specific grating functions: <instrument><grattype><order>Dyyyy-mm-dd><ccnm>N<version>.fits
NOTE: Use no underscores or additional tags. Use no dashes excluding the date convention above. Here are the allowed values:
-
<detnam> - acisi, aciss, acisn (n=0,9), hrci, hrcs, hrma, acap, acar, rwa, gyro, fssa, cssa (DO NOT USE "grating".)
-
Exception 1 above: <instrument> - acis, pcad, hrc, sim (DO NOT USE "tel".)
-
Exception 2 above:
<grating> - hetg, letg
<grattype> - heg, meg, leg (DO NOT USE "leg" with "letg")
<order> - [p|m|b]n (n=0,1,...); p(lus), m(inus), b(oth) not required for n=0
<effective date> - Observation date after which these data may be used. For BCF's this may not be trivial, requires CAL group input. NOTE: Effective date is NOT the file creation date in general!
<ccnm> - see table below for translation of CCNMmmmm keyword values to <ccnm>
<version> - this is determined by what is already in the CALDB for a given effective date. It is therefore set by the manager.

Required Keywords
MISSION = 'AXAF' TELESCOP= 'CHANDRA' INSTRUME= 'ACIS'/'HRC'/'HRC-I'/'HRC-S'/'TEL' DETNAM = 'NONE'/'ACIS-n'/'HRC-I'/'HRC-S'/'HRMA'/'GRATING' / Default: NONE FILTER = 'NONE' / Default: NONE GRATING = 'NONE'/'LETG'/'HETG' / Default: NONE EXTNAME CONTENT HDUCLASS HDUCLAS1 HDUCLAS2 HDUCLAS3 CCLSmmmm CDTPmmmm CCNMmmmm CBDnmmmm / Default: no boundaries CVSDmmmm= 'yyyy-mm-ddThh:mm:ss' / Start date and time of validity in TT CVSTmmmm= 'hh:mm:ss' / Start time of validity in TT CDESmmmm
The CVSTmmmm keyword is added to accommodate the HEASARC indexing software, which does not at this point use the FITS Y2K standard for the CVSDmmmm keyword illustrated above. The hh:mm:ss are to be specified in both CVSD and CVST keywords, and must be identical.
TELESCOP is to be set to 'CHANDRA' for CALDB files until further notice. INSTRUME='HRC' is allowed and will be assumed to apply to both HRC-I and HRC-S.
For documentation on the CALDB required keywords, see Required/Recommended FITS Keywords for Calibration Files.
Section 3 is especially important. It defines the syntax of the CBDnmmmm boundary keywords that specify the restrictions on applicability of the CALDB HDUs. Below, I have generally set CBDnmmmm='none', indicating that the files apply to the entire instrument or detector. However, individual HDUs in the files may be subject to restrictions and CBDnmmmm keywords should be added as appropriate. An example would be a PSF HDU that covers energies 1-8 keV and off-axis angles 0' - 10':
CBD10001= 'ENERG(1-8)keV' CBD20001= 'THETA(0-10)arcmin'
If there are no boundaries, CBDnmmmm keywords should be omitted.
