| System | alfosc |
| Command | calibexp |
| Arguments | [-e] [-f] [-n <nn>] [-o <ObjName>] [-lmi] <lampID> <tt> |
| Type | DET |
| Short Description | Sets ALFOSC calibration items up for a calibration spectrum with lamp <lampID>, take <nn> calibration images of exposure time <tt>, switch off lamps and, if not -lmi is given, take out mirror. With <lampID>=He/Ne/HeNe/ThAr/Halogen . |
| Long Description | Script for making a calibration spectrum with ALFOSC. Possible arguments are:
- -e echo mode: do not execute commands, only echo them
- -f fast mode:
script will return during the readout of the last exposure
- -n <Nexp> optional number of exposures (default=1)
- -o <ObjectName> optional ObjectName
- -lmi if set the mirror will stay in the beam at exit
- <lampID> with <lampID>=He/Ne/HeNe/ThAr/Halogen
- <exptime> exposure time
Sets the ALFOSC calibration items (mirror & lamps) up for a calibration spectrum, takes the calibration image(s) of which the last one in the background, switches off lamps, and per default takes calibration mirror out at exit. Switches autosave_on, and leaves it on. Moves FAPOL out if necesary. Sets header IMTYPE to FLAT/WAVE . If an <ObjectName> is given (double quoted if containing spaces), then the string will be added to the already present lamp specifier in the OBJECT FITS keyword. If CNTR-C is pressed the ongoing exposure will be aborted, and the calibration mirror will be moved out of the beam. NOTE: the last exposure will be taken in the background, so that instrument setup can be done during readout.
Usage example:
alfosc.calibexp -n 2 Halogen 15 Makes 2 halogen flatfield images with individual exposure time of 15s. |
