15.3. CALIBRATION DATA STRUCTURE (CDS) 173
CAL-G file CDS mnemonic description
basic calibration libraries:
CSCGCROSS CROSS SW noise/cross talk decorrelation matrices
CHCGCONV - house keeping interpolation values
CCG*DEAD a *DEAD dead pixel map
CCG*DARK a *DARK dark current exposures
CCG*DFLT a *DFLT detector flat field library
CCG*OFLT a *OFLT optical flat field library
CCG*SPEC a *SPEC filter & CVF spectral data
CSWCVF SWCVF SW CVF description
CLWCVF1 LWCVF1 LW CVF1 description
CLWCVF2 LWCVF2 LW CVF2 description
CCG*SLP a - CVF spectral line profile
CCG*PSF a *PSF point spread function library
IFPG IFPG focal plane geometry
- *GAIN gain conversion table
CWHEELS - CAM wheels information table b
ORBIT - ISO orbital parameters b
higher level calibration libraries:
- *AMDIST polynomial distortion coefficients
- *XFLT distortion flat
CCGLWDMOD LWDMOD parameters for the time dependent dark corrections
CCG*TRANS a *TRANS model transients
CCG*LINEAR a *LINEAR linearity correction library
CCG*FRAME a *FRAME detector astrometric calibration
CCG*GLITCH a *GLITCH glitch Model
CCG*STRAY a *STRAY non-dark local light model
a One CAL-G file or CDS exists for each CAM detector: replace * with LW or SW for full name.
b See Section 15.4 for an alternative handling of these data.
Table 15.1: The calibration data and associated CDS mnemonic used for naming purposes (see
Section 15.3.1 for CDS naming convention). A missing entry denotes that a CDS does not exist
for that CAL-G file – in the case of the CWHEELS and ORBIT data these are handled in an
alternative manner by CIA (see Section 15.4). Refer to Section 9.3.5 for further information
on CAL-G files and where they may be sourced. Also your attention is drawn to the ISOCAM
Handbook and ISO Data Product Document for more detailed information on the contents of
CAL-G files.
