General Description

This is a spectroscopic run, with 4 OBs that are the same.
The target is an edge-on spiral that is lensing a background quasar
and splitting it into two images.
The OBs have a blind offset from a red reference star (r~20.5, r-i~1.5)
and acquisition of the target in a narrow 0.5" width slit.
The slit needs to be oriented along the galaxy edge as to take the spectrum 
of the whole galaxy to measure its rotation curve (see finding chart).
The two images of the quasar may be useful for reference during the acquisition,
 they are separated by approx 0.8".
The slit should run approx perpendicular to the line joining the two QSO images
 (see finding chart).
Note that the slit should not be centered on any of the quasar images. 
It should be centered on the galaxy.
After acquisition, there are two exposures of 1080s with a small
dither along the slit between them for each OB.
