spectral-lines

spectral-lines uses the information in an observation definition file to calculate the expected locations, on each chip, of spectral lines. as well as their location on an 8-chip mosaic. Output is a file containing coordinate information, aperture type, and object name.


USAGEspectral-lines -o observset -l linefile -b binning [-c] [-e]
INPUT
observset.obsdef is the applicable observation definition file
linefile is a file containing a list of
wavelengths of lines to be plotted
binning is the binning of the CCD data
OUTPUTobservset.xy aperture data file
PARAMETERSnone


Details:

The binning parameter can be a single number (1,2,4) or a double number (i.e. 12) if binning is different in the x and y directions. If linefile is a number (i.e. contains no alphabetical characters) it is interpreted as a single wavelength for the linelist. If the flag -c is included, spectral-lines calculates the positions of objects along the slit rather that the slit center; if the flag -e is included, the two ends of the slit are marked instead.


Each line of the output file has the following format:

X(mosaic)   Y(mosaic)   Object #    ObjectName   Chip      X(ccd)     Y(ccd)  Wavelength
