alfosc |
alfosc.remote-slitoff |
[slit=<slitno>|xref=<x> yref=<y>] xstar=<x> ystar=<y> [xbin=<xbinning> ybin=<ybinning> xbeg=<x window begin> ybeg=<y window begin>] |
Calculates the telescope offset required to bring a target onto a given slit and performs the required telescope offset. See the ALFOSC Sequencer Command and Script Reference for a full description. |
TEL |
alfosc |
alfoscfocus |
[-d] [ready] [step] <n> |
Moves ALFOSC internal focus to step position <n>. [ready] Returns '0' if the element is moving, '1' if it is ready. [step] returns the step position [0-2700] of the ALFOSC internal focus. |
INST |
alfosc |
autosave_off |
[-d] |
Turns off autosave. |
DATA |
alfosc |
autosave_on |
[-d] |
Turns on autosave. |
DATA |
alfosc |
focus-auto |
<step-size> [<image>] |
Computes the best focus value from a focus sequence image <image> taken with the command focusexpose with focus step-size <step-size>. If no filename is given, the last obtained image name will be used. |
DATA |
alfosc |
focusexpose |
[-d] <nnnn> <mm> <tt> |
Makes a focus exposure. <nnnnn> is the focus start value, <mm> is the step size and <tt> is the exposure time per sub-exposure. 7 sub-exposures will be made. |
DET |
alfosc |
gainron |
[<file>] |
Computes detector gain and read-out-noise based on two bias frames and two flat fields, <file> being the last in the sequence. If no filename is given, the last obtained image name will be used. |
DATA |
alfosc |
qc-script |
|
Takes beta-light bias frames and flat fields for ALFOSC quality control. Calculates gain and read-out-noise. |
DET |
alfosc |
read_alfosc_setup |
|
The command instructs the ALFOSC instrument user interface (UIF) to re-read the setup information. The corresponds to pressing the "read setup" button in the UIF. |
INST |
alfosc |
tiasgat |
|
Script for aligning ALFOSC optics. See ALFOSC staff pages for instructions. |
DATA |
alfosc |
vgalign |
[-e] [exptime] |
