FIT [OI] FLUXES AND WAVELENGTHS

This step uses IFSFIT to find the wavelength of [OI]6300 for each
spaxel to make tweaks to the wavelength calibration.

DAR

IDL> ifsr_dar,'/path/to/data/cube.fits',4,4,xranf=[15,33],yranf=[15,35],xranp=[21,23],yranp=[24,26],/circ,sig=10

COMBINE DATA

Line up data by finding a common peak.

> cube = ifsf_readcube('/path/to/data/dcube_a.fits',/quiet)
  peak = ifsr_peak(cube,[6400,6800],xranf=[15,33],yranf=[15,35])
Peak flux at [21.9,24.7] is 1.89E+00
X/Y-widths: 2.76 / 2.69
  ...

Mosaic data:

> ifsr_mosaic,['dcube_a.fits','dcube_b.fits',...],'/path/to/output/file.fits',indir='/path/to/input/data/'

TELLURIC CORRECTION

IDL> ifsr_telcor,'/path/to/input/file.fits','/path/to/output/file.fits,'/path/to/telluric/correction.fits',am=1.05,wvcor=0.25

ROTATION

Cube has to be rotated to achieve correct orientation.

- If you want a subsampled linemap (by, e.g., a factor of 10) then you
  can add these keywords:
  subsamplefac=10d,subsampleout=’output_subsampled_linemap.fits'

- If you want the routine to include negative fluxes when doing the
  continuum subtraction (depends on the situation), add the keyword
  /allowneg.
