If an observation with ACAM is required at short notice, it's helpful to know the approximate focus offsets from best focus for ISIS and LIRIS. These are usually ~ +0.27 mm and ~ -0.08 mm respectively (the latter for ACAM with the Sloan-g2 filter relative to LIRIS with the jc filter, measured 18/3/11).

Example 1. Imaging sequence with slow readout, no binning, biases (~20 min).

acaminit slow 1 [acquire object and autoguide] acamimage BESB glance acam 30 [take a glance image, check S/N and adjust exposure time accordingly (glance image is stored as s1.fit)] run acam 300 "NGC4532 BESB" acamend [obtain dome or sky flats at twilight]

Example 2. Imaging sequence with fast readout, binning 2, 5-arcsec dithering, biases (~18 min).

acaminit fast 2 [acquire object and autoguide] acamimage SlnR multdither acam 6 120 5 auto_on "C101 SlnR" acamimage SlnI multdither acam 10 120 5 auto_on "C101 SlnI" acamend [obtain dome or sky flats at twilight]

Example 3. Imaging sequence with 10-arcsec dithering, autoguiding on in one filter, and autoguiding off in another, no binning, slow readout, biases (~45 min).

acaminit slow 1 [acquire object and autoguide] mcol acam "Override" on 10 "BESI,3,600,auto_on" "BESR,3,100,auto_off" acamend [obtain dome or sky flats at twilight]

Example 4. Spectroscopy sequence when LIRIS, or a NIR instrument, is mounted at Cassegrain, slow readout, binning 1x2, no sorting filter, arcs, flats and biases (~33 min).

Example 5. Imaging and spectroscopy sequence when ISIS, or an optical instrument, is mounted at Cassegrain, no binning, slow readout, no sorting filter, arcs, flats and biases (~36 min).

Example 8. Imaging and spectroscopy sequence, optical instrument at Cassegrain, no autoguiding; fast readout and binning 1x1 for imaging; slow readout and binning 1x2 for spectroscopy, no sorting filter (~29 min).
