important GUI check list:
setup IMACS:
for spectra:
FILTER = 'Spectroscopic2'
DISPERSR= 'Gri-300-17.5'
SLITMASK= 'FourS_2471'
for acquisition images:
filter : sloan r'
DISPERSER = f/2 imaging
SLITMASK = f/2 imaging
slit: FourS_2471 will put the entire spectrum in CCD8
BINNING 1 x 1
setup of TOSLIT and ICOBJECT:
take short 1 second exposure fast readout with IMACS GUI, just ambient
light.
FILTER=Spectroscopic f/2
DISPERSER=None
SLITMASK=FourS_2471
display CCD8 in ds9, use IRAF imexam "k" to measure the
position of the slit.
set up for TOSLIT
CCD 8: xoffset = 2270 - x(slit); yoffset = 4200 - y(slit)
last time xslit = 540 yslit=1730.4, therefore
XOFFSET= 2270-540
YOFFSET= 4200-1730.4
parameters for TOSLIT camera = SHORT for f/2
(camera = "short") Camera ('long' or 'short')
xbin = 1
ybin = 1
xoffset = xOFFSET from above
yoffset = yOFFSET from above
Parameters for ICOBJECT
camera short f/2
xpos = position of SLIT (not offset) PIXEL position
ypos = position of SLIT (not offset) PIXEL position
Acquisition images r' band 60 seconds,
you can do this twice. first offset should be about 20 arcseconds.
the second one about 0 arcseconds.
please take these 2 spectroscopic standard stars, one red and blue
details later
AFTER each science image. tell operator you're taking lamps,
put in flatfield screen.
take, 1x8 second QH flat, and 1x2 seconds HeNeAr lamp.
(note .. don't turn on last He lamp ?? check with instrument specialist)

TARGETS:
DES15C1mvx 03:39:32.06 -26:43:27.7 mag 22.6
(try this one first, if you don't see it, skip it)
try 30 minutes, if you see a faint trace, then do another 2x30 minutes.
If you have time, and the airmass isn't too bad, do these
DES15C1nfb 03:37:49.93 -27:01:10.6 1x30 minutes mag ~20.5
on a bight galaxy, remember to change the grey scales when running
icobject to see the point source (supernova) on the galaxy
DES15C2njv 03:36:29.87 -28:34:11.5 1x30 minutes mag ~20.4
on a bright galaxy,
star name
acquisition exposures 5 seconds.

note on DES finders:
The GREEN square is centered on the host.
The RED square is centered on the supernova.
try to get/align the object in the RED square into the slit.
HELPFUL HINT: in ds9 (on IMACS CCD8 image) use zoom to flip X and Y,
then the image in ds9 and the finder will be in the same orientation,
but perhaps not the same angle.
