We need to extract and concatenate the correct SCDs in order to make a raster PDS
containing data acquired with the same entrance wheel parameter. First we clean the
SSCD and eliminate all SCDs that have obviously too few IMAGES to be valid. In this
example, cleaned sscd splits the SSCD into two segments –an unnecessary side-effect due
to limitations in the design of the SSCD and the CAM05 observing mode. We can however
easily recombine the SSCD segments:
CIA> cleaned_sscd = sscd_clean( sscd, minimum=20 )
CIA> sscd_del, sscd
CIA> sscd_concatene, cleaned_sscd[0], cleaned_sscd[1]
2. The next step is to create a new SSCDs containing SCDs from a single entrance wheel
parameter setting. This we can do with scds select:
CIA> sscd_polar1 = $
scds_select(cleaned_sscd[0], ’polar1’, ’entwhl’, ’POLARIZOR 1’ )
CIA> sscd_info, sscd_polar1, scds, /pol
