11.1. CIA PROCESSING OVERVIEW 75 2. Data calibration refers to the process of dark correction, deglitching, stabilisation and flat-fielding of your ISOCAM images. Though this is a highly complex process, CIA handles it transparently via a set of high level routines. The basic process of calibration is: (a) After slicing your data you make a PDS from the set of SPD SCDs you have created in the slicing process. This is done with one of the CIA routines, get sscdraster, get sscdstruct or get sscdcvf, depending on your observation type. (b) You perform the calibration on the PDS with the core calibration routines (see Section 13.2.1). Note that it is possible (and sometimes desirable) to directly perform calibration on the SPD SCDs. All the core calibration routines are capable of accepting an SSCD as input. Chapter 13 describes in more detail the process of calibration. When your data are calibrated you are ready to move on to the final step of image display. 3. Image analysis & display refers to the presentation of your calibrated ISOCAM images. (You can also display the images in the AA calibrated images in the AAR data product directly - this you may have already done in Chapter 10.) CIA provides routines to do the following: • Display images from the AAR data products with sad display. (See Section 10.2.) • Examine the temporal behaviour of pixels with xcube and x3d. (See Section 14.4.3 and Section 14.4.5 respectively.) • Overlay your CAM images with optical images (or indeed any counterpart images) isocont. (See Section 14.6.2.) • Interactively choose contours for contour plots with xcontour. (See Section 14.7.1). • Create postscript plots.
