CSET-Interactively set regions of a spectrum to a constant value

Description:

CSET is an interactive program that takes a displayed spectrum and allows the user to select regions that are to be set to constant values. This can be used, for example, to set regions in a B star calibration spectrum to 1., so that they will have no effect when used with BSMULT.

Parameters:

VALUE

CSET lets you select regions of an already displayed spectrum, which are then set to a constant value. This value can be changed if required, but this is the initial setting for it.

OUTPUT

CSET generates an output file that is essentially the data from the displayed spectrum, with certain regions set to constant values. OUTPUT is the name of the resulting spectrum.

QUIT

Used to confirm quitting area selection.

 C S E T

 Figaro function to set large interactively selected regions
 of a spectrum to a constant value.  This is intended mainly
 for use in generating mask spectra, or modifying calibration
 spectra such as those used by BSMULT.  CSET assumes that a
 spectrum has already been displayed by SPLOT, and will generate
 a new data structure based on the spectrum displayed, with
 only the data changed.

 Command parameters -

 VALUE       (Numeric) The value to use for the selected regions

 OUTPUT      (Character) The name of the output file to
             be created.  If this is the same as the displayed
             spectrum, the data in the displayed spectrum will
             be modified.

 Command keywords -

 QUIT        Used to confirm quitting area selection.

 User variables used -  (">" input, "<" output)

 (>) TVFILE  The name of the displayed spectrum
 (>) TVXST   The first displayed x-value
 (>) TVXEN   The last displayed x-value
 (>) TVHIGH  The maximum displayed y-value
 (>) TVLOW   The minimum displayed y-value
 (>) TVCOLOR The GRPLOT code for the plot colour
 (>) SOFT    The device/type string defining the display device
