GSPIKE-Generates a 'spiketrum' from a table of values

Description:

Given a template spectrum - from which it gets the wavelength range required - and a table file giving wavelength and data values, GSPIKE generates a 'spiketrum'; a spectrum where all the elements except for those at the tablulated values are zero.

Parameters:

SPECTRUM

A template spectrum to determine the wavelength range over which to generate the 'spiketrum' from tabulated values. Must have a proper array of X values.

TABLE

The name of the table file holding the pairs of values (wavelength and data) for the points to be used to generate the 'spiketrum'. If no extension is specified, .TAB will be used. The table may be in any of the standard Figaro directories, or in the current default directory. Or it may be specified in a form that includes the directory name.

SPIKETRUM

The name of the resulting 'spiked spectrum' (hence 'spiketrum') produced by GSPIKE. It will always be a new file.

 G S P I K E

 Generates a 'spiketrum' from a table of X and Z values, given a
 spectrum to use as a template for the X range to be used.  The
 resulting spiketrum will be a spectrum with the same .X structure
 as the template spectrum, and a .Z structure that has zeros
 everywhere except at the points given in the table.  The table file
 can include SET commands that set individual item values in the
 resulting file, but the item names need to have been defined in the
 file SPIKETRUM.DEF.

 Command parameters -

 SPECTRUM    (Character) The name of the template spectrum.
 TABLE       (Character) The name of the file containing the
             table of X and Z values.  If TABLE contains no
             extension then '.TAB' will be assumed.
 SPIKETRUM   (Character) The name of the spiketrum to be creeated.
             Note that this will always be a new file.

 Command keywords -  None

 User variables used - None
