How to work with scam_routines.pro
------------------------------------------------------------------

1. startup IDL

% idl

2. compile scam_routines

IDL > .r scam_routines

3. plot scam data in all-sky map

IDL > plot_scam,'2012012222000096_E04.0G5S0152F2B1.abs'

4. plot scam data on polar map in geographic coordinates
   (projection altitude is 300 km in default)

IDL > plot_scam,'2012012222000096_E04.0G5S0152F2B1.abs',/map

5. change projection altitude

IDL > plot_scam,'2012012222000096_E04.0G5S0152F2B1.abs',/map,alt=250
