172 CHAPTER 15. CIA DATA STRUCTURE HIGH-LEVEL ARCHITECTURE
3. CREATION: Contains details about CDS owner and CDS creation time. Type: string
array.
4. DATA: The calibration data is held in this substructure. DATA is in fact an array of
IDL structures. Each structure holding a calibration record and the number of structures
in the array is equal to NUMBER. (See Section 15.3.2.)
5. NUMBER: Refers to the number of records in the substructure DATA. A record corresponds
to a single independent calibration measurement (such as a DARK image) and
associated CAM parameters.
15.3.2 CDS and CAL-G files
The different types of calibration data (i.e. CAL-G files) and the CDS name for each is given
in Table 15.3.2.
An example of how the subfields of DATA would look for a CDS containing DARK images is
given below. The index, i, refers to a particular record within the DATA field, where the range
of i is: 0 ≤ i calg_dark_dir = ’DKA200:[MDELANEY.P0007780.14300601.OTHERS.CCGLWDAR]’
If you are using UNIX, the notation is:
CIA> calg_dark_dir = ’/home/mdelaney/p0007780/14300601/others/CCGLWDAR’
