Continue initializing the three mechanisms; the slit unit and the two filter wheels:
Test the range of the mechanisms and prepare to take a spectra:
acamslit -p 8
acamslit -p 4 (1" slit)
acamwh1 7 (empty)
acamwh2 6 (deploy the VPH (Volume Phase Holographic), called V400)
rspeed acam slow
window acam 1 "[1:2148,800:3300]"
bias acam (Take bias frame)
Examine the image; record bias level and noise in log book.
agacamcal (set flat to direct comparison lamp light to ACAM, smallfeed)
with LIRIS: complamps cune
any other: complamps cune+cuar
arc acam 1 (Take an exposure, store as rnnnnnnn.fit)
The combined CCD status window will show the state of progress as the exposure is read.
Make sure the spectra gets written (with TCS header information when tracking) to the Observing Log.
Examine the image; are arc lines visible?
Open the mirror petals and switch on the low power top ring flat field lamp (set
the intensity to 3/4 on eng. console).
With ACAM there is no need for any of the three 500W lamps.
agacam (set flat to direct light to ACAM, largefeed)
acamslit -p 1 (is a filter holder present
in this position, the FOV will be vignetted!)
acamwh2 n (where 'n' is the position (1-6) of a broad band filter like HarV4, BesR, SloGunR or SloGunI)
flat acam 1 (Take an exposure, store as rnnnnnnn.fit)
The combined CCD status window will show the state of progress as the
exposure is read.
Make sure the image gets written (with TCS header information when tracking) to the Observing Log.
Examine the image; is the image evenly illuminated and not saturated?
The image should on one side extend to the edge of the chip. Is the image perfectly round suspect vignetting and check no filter holder has been left in position 1 of the Slit Unit.
Close mirror petals and switch off top ring flat field lamp.
