alfosc |
alfosc-calibs |
[-e] [-skip] <date-string> |
Script to do biases and spectral calibs for all setups and windows used in a particular night.
Of course, this script should not be used for previous nights in case optical elements have been changed since. The wheel setups are checked for inconsistencies in current vs stored wheel position content. Any such inconsistent setup will be skipped, with a warning on the talker.
Command-line arguments:
[-e] echo mode: only show what will have be done in case started without the -e flag
<datestr> for expample 'ALwb13'
Spectroscopic and window setups are collected from the FITSheader database.
For all different window setups bias frames will be taken.
For all different setups with a grism in the beam, spectroscopic flats and arc-lamp spectra will be taken.
For flat/arc exposure times, alfosc.callampstimes is used. Setups that are yet non-supported by alfosc.callampstimes will automatically be skipped, with a warning on the talker
When the flag -skip is given, the user is asked to specify interactively
from which GRISM or WINDOW setup to (re-)start alfosc-calibs.
Is supposed to work also for spectropolarimetry.

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"

qicpol |
[<2ndfile>] |
Circular polarimetry quick-look tool (FAPOL+ calcite) which calculates the circular polarization from a set of two images (retarder plate positions 0 and 90.0 degrees). The flux of each image is measured with fixed aperture using iraf/apphot from raw images. See more detailed description of the script from here |
DATA |
alfosc |
qilpol |
[<4thfile>] |
Linear polarimetry quick-look tool (FAPOL+ calcite) which calculates the linear polarization from a set of four images (retarder plate positions 0, 22.5 45 and 67.5 degrees). The flux of each image is measured with fixed aperture using iraf/apphot from raw images. See more detailed description of the script from here. |
DATA |
alfosc |
quickspec |
[<file>] |
Extracts spectra and applies an approximate wavelength calibration on an ALFOSC spectroscopic image using the iraf tasks apall and dispcor. If no file is specified, spectral extraction from the last image written to disk will be attempted. Extracted spectra are kept in the directory /data/reduced/alfosc/ on the instrument computer. Existing spectra will be overwritten if the task is re-run on the same file. The wavelength calibration is done using standard wavelength settings for the standard horizontally oriented central slits. The wavelength calibration is only approximate, and is most likely based on a slit that you are not currently using. Note that the slits have different Y-positions and hence different wavelength zeropoints, and that hence zeropoint offsets of for instance 200 Ångström are normal. The quickspec will leave the user in an IRAF splot session. To kill the session type q in the postprocessing graphics window. There are 2 ways of initiating quickspec. Automatic (see command quickspec-config auto=yes below), and from the sequencer command line. * When called from the sequencer command line, all input and output will go through that sequencer terminal. * When automatic, the input and output goes through the BIAS 'command' window. |
DATA |
alfosc |
quickspec-config |
[<options>] |
Use this command to set the IRAF apall task parameters used in the quickspec script. auto=[yes|no] : Automatically run quickspec on incoming images
kill=[yes|no] : Automatically remove previous quickspec windows
default : loads default values. Below parameters are specific for the apal iraf task: background=[none|average|median|minimum|fit] weights=[none|variance] clean=[yes|no] edit=[yes|no] nfind=[1-10] (useful for Echelle spectra, MOS spectra, spectropolarimetry, and longslit spectra with more than one object on the slit) If the command is issued without any options, current parameter settings will be listed. |

DATA |
alfosc |
tweakmos |
[-e] <MASKfile.fits> <FIELDfile.fits> |
The routine will first display the mask image, and the user has to identify the fiducial holes one by one, using the pointer (please follow the on-line instructions in the Sequencer terminal).
Position the cursor over a fiducial hole and press 'a' (for centroiding) or 'x' (for cursor coordinates). This can be done multiple times until satisfied. When ready to go to the next hole press 'n'. Repeat until all fiducial holes are identified, and then press 'q'.
When all useful fiducial holes are marked, the object field is displayed and the position of the first alignment hole will be marked with a blue circle. Now try to identify the corresponding star on the image.
Position the cursor over the star corresponding to the blue circle and press 'a' (for centroiding) or 'x' (for cursor coordinates). This can be done multiple times until satisfied. When ready to go to the next star-hole pair press 'n'. Repeat until all fiducial stars are identified.
