16.2 An example of SAD manipulation
In Section 10.2 we used sad display to create SADs from the AAR data products. At that
point you were probably only interested in a quick look at your data – now we will delve a little
deeper into the data and take a look at the SADs themselves.
Most likely you have exited the session where you first used sad display to look at your
AAR data products. To regenerate the SADs in a CIA session, use sad display as described
in Section 10.2, or if the SADs are on disk use ssad read.
Upon exiting sad display all the SADs created will remain in memory. Try the following
command:
CIA> print, ssad_list()
CSSA000014300601_96091713360439 CSSA000014300601_96091713360451
ssad list lists all the SSADs in memory. Two such SSADs exist in our example, one catalogues
the set of SADs that hold the EXPOSUREs from the CCIM and CMAP data products
and the other the SADs that hold the set of MOSAICs from the CMOS data products. The
former SADs are known as origin SADs and the latter as future SADs. To see the full set of
future SADs we can use the CIA routine ssad elem. Given the name of an SSAD it will list all
of its SADs:
CIA> print, ssad_elem( ’CSSA000014300601_96091713360451’ )
CSAD000014300601_96091713370548 CSAD000014300601_96091713370625
CSAD000014300601_96091713370691
In this case there are two future SADs, with a MOSAIC in each, and a third SAD, containing
the contents of the AAR data product CSSP, which you can ignore. Listing the origin SADs
catalogued in our second SSAD we see that there are many:
CIA> print, ssad_elem( ’CSSA000014300601_96091713360439’ )
CSAD000014300601_96091713360476 CSAD000014300601_96091713360767
