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
