Calcium filter

Open a terminal and go to the directory where the IDL routine is located:

cd /home/dot/santi/idl

Enter IDL and launch the routine that scans the line and plots the profile (replace initialvalue with the wavelength you want to start from and numberofpositions by the number of points you want to scan along the line in steps of 0.05 Ångstroms.

plot,(p=ca_init(initialvalue,np=numberofpositions))

Red continuum filter

Open a terminal and go to the directory where the IDL routine is located:

cd /home/dot/santi/idl

Enter IDL and launch the routine that scans the line and plots the profile (replace initialvalue with the amount of degrees you want to start from and numberofpositions by the number of points you want to scan along the line in steps of 0.05 degrees.

plot,(p=rc_init(initialvalue,np=numberofpositions))
