System | Command | Arguments | Description | Type |
alfosc |
imexam |
|
Initiates an IRAF imexam session on the image currently loaded into the ALFOSC DS9. While active in the imexam session, no further commands can be issued from the sequencer window. To kill the imexam session type q on the image in the postprocessing display.
CURSOR KEY COMMANDS:
? Print help

c Column plot
e Contour plot
f Redraw the last graph
j Fit 1D gaussian to image lines
k Fit 1D gaussian to image columns
l Line plot
m Statistics
image[section] npixels mean median stddev min max
q Quit
r Radial profile plot (see above for output)
s Surface plot
x Print coordinates
col line pixval [xorign yorigin dx dy r theta]

DATA |
alfosc |
log-comment |
"Comment in quotes" [file1 file2 ...] |
When invoked with just the comment, it will be applied to the latest available image with a prefix for the current night (which starts at noon) and the sequencer's instrument.
If image names are provided, the program will test the existence of ALL them before applying the change.
Eg.
$ alfosc.log-comment "This is a comment"
$ alfosc.log-comment "Comment for two" ALug170154 ALug170155
Notice that there's no need to add the ".fits" after each image's name
If no arguments are provided, a usage message is displayed |
DATA |
alfosc |
object |
[-d] <text> |
Sets the FITS keyword OBJECT to <text>. |
DATA |
alfosc |
photstd |
[-e] [-a mode] [-f filterIDs] |
Automatic exposure of standard stars.
Goes to nearest standard field and does exposures in filters UBVRi as default - or filters specified by the user.
Currently supports UBVRi and
in the future sdss ugriz. Other filters can be done, but will have the same exposure times, set by the variable default_time.
Instead of going to the nearest field, aquisition mode can be set to a specific target. The TCS name must be used, see http://www.not.iac.es/instruments/alfosc/photstd/.
Usage example:
alfosc.photstd -a A_PG1633+099 -f "74 75 120 110"
|
DATA |
alfosc |
rempath |
[-d] <nn> |
Sets the remote saving path to <nn>. |
DATA |
alfosc |
remsave_off |
[-d] |
Turns off remote saving. |
DATA |
alfosc |
remsave_on |
[-d] |
Turns on remote saving. |
DATA |
alfosc |
reset-log |
|
The script will use infosys.kill to reset the monitoring system, then it will wait for a set number of seconds, and at last it will instruct the obslog to show the listing for alfosc, all the while informing the user about what is happening
If there's any error, the script will notify the user and suggest further actions. |
DATA |
In scripts, the syntax alfosc.<command> should be used.
If a part of a command is written in <angle brackets>, this is an argument that should be replaced with a value.
If a part of a command is written in [square brackets], this is an optional argument or flag.
When available, the optional flag -d will write extended debugging information to the log.
When available, the optional flag -e will show the script on standard output instead of executing the commands.
When available, the optional flag -t will only make a simulated exposure. Useful for testing scripts.
Type definitions:
DATA: All commands related to handling/modifying data (editing fits-headers, post-processing etc.).
DET: Commands related to operations with the detector.
DISP: Commands related to displaying images on the instrument computer.
INST: Commands related to operations with the instrument.
TEL: Commands related to operations with the telescope.
