qplot runs either xcsao or
emsao to check previously computed
redshifts which have been stored in the spectrum's VELOCITY and
other keywords by either or both programs. The spectrum is displayed
interactively by whichever program is specified by the qtask
parameter, and the user may modify the results, flag their acceptability,
or simply exit without modifying the file.
- spectra file or list of files
- Use this as the first argument to either xcsao
or emsao as specified by qtask.
- qtask xcsao
- Use this task to display the spectra.
- velplot combination
Plot the labelled lines at this redshift, which may be combination,
emission, or correlation. If the given velocity has
not been set in the image header, a redshift of zero is used.
