Flux-###.fits :
Contains spectrum of object in 2-D format (each row is
an echelle order). This may or may not be wavelength
calibrated with the coeffecients of polynomial fits
contained in the FITS header.
Err-###.fits :
Contains (one sigma) formal error
spectrum for the object in 2-D format.
Sky-###.fits :
Contains the sky or background
spectrum derived from the sky
region on either side of the object
spectrum. The level corresponds to
the counts observed in 1 pixel of sky
at each wavelength point divided by
the rescaled flat field (see Flat-###.fits.)
Take a look at
sky notes
for information of converting the sky spectra
to (approximate) flux units.
Flat-###.fits :
Contains the spectrum of the flat
field (quartz lamp) exposure scaled
by some arbitrary value. The level
corresponds to the counts in 1 pixel
at each wavelength point scaled by
an arbitrary value.
s2n-###.fits :
Contains the signal-to-noise (one
sigma) per pixel corresponding to
the object spectrum. (This is found
by dividing Flux-###.fits by Err-###.fits .)
DN-###.fits :
Contains the digital number (or
count level) spectrum for the object.
(This is found by multiplying
Flux-###.fits by Flat-###.fits .)
This is the total counts observed in
the object at each wavelength point (minus the sky background.)
