80 CHAPTER 12. DATA SLICING CIA> nscd = sscd_get( ’nscd’, erd_sscd ) CIA> print, nscd 41 Using a simple IDL loop we can convert all the ERD SCDs to SPD SCDs in one line: CIA> spd_scds = strarr( nscd ) CIA> for i = 0, nscd - 1 do spd_scds[i] = erd2spd( erd_scds[i], $ CIA> ssid=erd_sscd, /del) Note that the del keyword is set to delete the ERD SCDs from memory as the SPD SCDs are created. Finally, for convenience create a new variable containing the name of the SPD SSCD. Since the name of SSCD is unchanged this is achieved by copying the variable erd sscd: CIA> spd_sscd = erd_sscd NowwecanremovetheoldERD SSCD and its ERD SCDs from disk. sscd remove to do just that. We can use CIA> sscd_remove, erd_sscd, dir=scd_dir Finally we can save the SPD SSCD with its new SPD SCDs. CIA> sscd_write, spd_sscd, dir=scd_dir 5. As an alternative to the above steps using spdtoscd we can directly create SPD SCDs in memory (and on disk) with the SPD data product: CIA> spdtoscd, ’cisp14300601.fits’, spd_sscd, dir=product_dir, $ CIA> scd_dat=scd_dir, ack=ack 6. Our next step is to find the data we require from the SSCD. The whole AOT is contained within the SSCD, but we may be only interested in a single CONFIGURATION. In our example here, we have a raster observation with two CONFIGURATIONs, one for filterwheel LW6 and one for LW3, and in addition several STATEs corresponding to internal calibrations and detector stabilisation. We can get an overview of the contents of the SSCD with sscd info – it lists important parameters of all the SCDs in an SSCD. (These parameters are simply values extracted from fields within the SCD structure.) The contents of the SCDs are in fact a history of the observation. Reading down through the list below you can see the behaviour of CAM through out the AOT. In particular, look out for which filter (the field FLTRWHL) and which OP-MODE (the field MODE) is given for each SCD. Remember, in this observation the filter defines the difference between the two CONFIGURATIONs.
