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
