description of task

CALIB

make_dirs.pro
(directory structure)
generates uniform directory structure for data products

stg0_st.pro/stg0.pro
/rega_NN/galfa.DATE.PROJ.####.rega.sav /rega_NN/galfa.DATE.PROJ.hdrs.rega.sav
removes bandpass, removes fiber reflections, doppler corrects, tags and truncates data from one day's observing of one region

XING SPMOD

spcor.pro
/aggr.sav /spcor_MM.sav
removes fixed pattern noise

xgen.pro
/xing/regaAA_BB.sav
finds all crossing points and generates a structure of locations and relevant parameters.

lxw.pro
/xing/regaAA_BB_l.sav
loads weighted spectra into crossing point structure

xfit.pro
/xing/regaAA_BB_f.sav
fits for the relative gain at each crossing point

lsfxpt.pro
/xing/rega_lsfxpt_NAME.sav
generates a least-squares fit matrix that relates crossing point gains to beam gain variability with time

xg_assn.pro
/rega_NN/rega_NN_xing_NAME.sav /xga_NAME.sav /xingarr_NAME.sav

solves the least-squares fit-matrix and applies the beam gain solution to all spectra

GRID

todarr.pro
/todarr.sav
generates a single structure with all position information for entire region

gridzalfa.pro
/sprs_GRIDNAME.sav
generates a sparse matrix that relates the time ordered data to a user-defined set of grid pixels

make_grid.pro
/GRIDNAME.sav
generates the final grid from the sparse matrix and gain coefficients
