It is necessary to select the filters which will be used for the analysis.
The are many ways to do this. An example is given below for the
Al.1 and Be119 filters:
IDL> i1 = where(GT_FILTB(new_index) eq 4) ; Get Be119 indices
IDL> i2 = where(GT_FILTB(new_index) eq 2) ; Get Al.1 indices
IDL> data1 = new_data(*,*,i1)
IDL> index1 = new_index(i1)
IDL> sat1 = sat(*,*,i1)
IDL> unc1 = unc(*,*,i1)
IDL> data2 = new_data(*,*,i2)
IDL> index2 = new_index(i2)
IDL> sat2 = sat(*,*,i2)
IDL> unc2 = unc(*,*,i2)
