CDS map objects

A CDS map object can be made from the data structure using

• IDL> qlds = readcdsfits('filename') ; read data
• IDL> cds_new_spike, qlds ; clean for cosmic rays
• IDL> nis_calib, qlds, /erg, /ster ; calibrate
• IDL> map_w0 = mk_cds_map(qlds, 0) ; make map

This will use the data from window 0 - check out the documentation on mk_cds_map to see what the analysis options are.

If you prefer to put an alternative data array (of the same dimensions) into the map (eg a velocity map) this is simply done by

• IDL> map_w0.data = my_vel_array
