Leave these!) # cycle_count <<5>> (no. of cycles where exposure time in .csx file) # bias <> # setup_array <> (option 1: read in indexed gap numbers; see below) # <> (option 2: generate gap numbers; see below) # etalon_start <<0300>> (start gap in option 2) # etalon_incremt <<0010>> (increment in gap in option 2; no. of steps in .csx file) # # **note: option 1 says, how many entries in the .csx files. Let's use these as index points # into the array filled by sel_fil_z_array. Type in each entry alone. This is the only # way to deal with irregularly sampled frequencies. # # You can always return to normal mode to do a glance, say, with "method default". Probably # best to do this after every shuffle since bombing in shuffle mode is not good. "Method # shuffle" gets you back after "method default". The long-slit shuffle mode is excellent for # calibrating where lines occur in a filter, as is the FORS cube mode. # # So there are in fact five different ways to drive/step the etalon. # # (i) change_cs100 gap and "run" # (ii) run_step # (iii) run_file # (iv) shuf_multi option 1 # (iv) shuf_multi option 2 # # Finally, to generate # # Issues remaining. Simply run the csx.f file below and trap the output. # # JBH (AAT 15/3/96) #--------------------------------------------------------------
