During an observing run, in order to make time-sensitive decisions about what to observe, a quicklook script is provided.
First, navigate to a directory you want the output data in.
Then, with at least one arc frame and at least one flat frame in /path/to/calibs run
to perform quick calibrations for the red and blue sides, respectively.
Then once you have a science frame (either in the same directory, or elsewhere) in /path/to/science/data, run
This step should be very quick (about 15 seconds for the red side, 8 seconds for the blue side), and each command will pop up a ginga window for you to inspect the sky-subtracted frame. Also, a GUI will pop up to display the fluxed spectrum for each object identified in the frame.
The quicklook script produces PypeIt 2D Spectrum and 1D Spectrum files, described in outputs.
