keck longslit
Quick-look at partially reduced longslit (low-D) ESI spectra from Keck observations of Katinka's HI-excess galaxies.
Processing so far:
-overscan
-bias
-flat
-remove cosmic rays (LACOS)
-rotation
To make the images below:
-average multiple exposures
-re-projection/transformation (to remove distortion, using lamps) to calibrate wavelength
-subtract sky lines
