Displaying individual spectrum files in IRAF
Please see the Reading individual
spectrum files for details on the spSpec FITS file
structure. In brief, though:
if you want to use splot in IRAF to plot a spectrum,
you want to give it a file name like:
spSpec-MJD-plate-fiber.fit[0][*,X]
where X=1 for reduced spectra
X=2 for spectra with 4th order fit to continuum removed
X=3 for the error array
X=4 for the mask array
Alternatively, you can also just give splot a filename
with the [0] extension at the end, then respond with the X from
the above list when it asks: Image line/aperture to plot.
Ex.
on> splot
List of images to plot (bob): spSpec-51821-0384-636.fit[0]
Image line/aperture to plot (0:) (0): 1
