specsens
Name
specsens– Calculate sensitivity curve
Usage
specsens specfile outfile stdfile extfile (airmass) (exptime)
(stdzp) (function) (order) (thresh) (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.
- stdfile
- 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
- (stdzp)
- Real. Zeropoint for the magnitudes listed in the stdfile for converting into fluxes.
- (function)
- String. Functional form to fit to the observation.
- (order)
- Int. Order of the function to be fit to the observations.
- (thresh)
- Real. Threshold for rejecting values in the obserations of the source.
- (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
SPECSENS calulates the calibration curve given an observation, a standard star,
and the extinction curve for the site. The task assumes a 1-D spectrum that
has already been sensed from the original observations.
