specal
Name
speccal – Apply sensitivity curve to observations
Usage
specal specfile outfile calfile extfile (airmass) (exptime)
(clobber) (logfile) (verbose)
Parameters
- specfile
- String. ASCII file contain the spectra of the calibration source. This
should be the output from specextract.
- outfile
- String. Name of an output file to write the calibrated sensitivity curve.
- calfile
- String. ASCII file that contains the calibrated magnitudes for the
source.
- extfile
- String. ASCII file that contains the extinction curve for the observing
site.
- (airmass)
- Real. Airmass of the observations
- (exptime)
- Real. Exposure time for the observation
- (clobber)
- Hidden boolean. If set to ‘yes’ files contained within the outpath
directory will be overwritten by newly created files of the same
name.
- (logfile)
- String. Name of an ascii file for storing log and error messages
from the tool. The file may be new, or messages can also be appended to a
pre-existing file.
- (verbose)
- Hidden Boolean. If verbose=n, log messages will be suppressed.
Description
SPECCAL corrections a given observation by a calibration curve
and the extinction curve for the site. The task assumes a 1-D spectrum that
has already been caled from the original observations.
