Making a Plot of the Sky Distribution of Pointing Observations     25 Apr 00

    A script called SHOW_POINT in TEL$POINTING can be used to make a polar
coordinate plot of pointing observations that have been made (or one with only
the coordinate grid which could be used as a template for plotting future
observations manually).  It reads the output of the GOOD_POINT program which
is used to extract pointing data from the archive, discarding bad fits, and
put the data in the correct format for the pointing model fit program.  To 
use it, first RUN GOOD_POINT, then type @SHOW_POINT <file>, where <file>
is the GOOD_POINT output file (or the word, TEMPLATE).  The script will 
automatically run GRAPHIC to make the plot then the GRAPHIC> prompt will be
given.  Type HARD/PL for a hard copy (if desired) and EXIT to end GRAPHIC. 

    GOOD_POINT is described in the memo, KDATA:[SMT.DOC]POINTING_FIT.DOC.  
Below is an example where the date is assumed to be April 25, the GOOD_POINT
output file is JUNK.PNT, and the standard GOOD_POINT filter parameters are
used. 

	SD TEL$POINTING
	RUN GOOD_POINT
	25APR
	JUNK.PNT
	3
	3
	(Any title you want here.  SHOW_POINT ignores this.)
	@SHOW_POINT JUNK.PNT

An example where the pointing data from two days, Apr 24 and Apr 25, are 
combined would be:

	SD TEL$POINTING
	COPY/CONC POINTING.DAT_24APR2000,POINTING.DAT_25APR2000 JUNK.DAT
	RUN GOOD_POINT
	JUNK.DAT
	JUNK.PNT
	3
	3
	(Any title you want here.  SHOW_POINT ignores this.)
	@SHOW_POINT JUNK.PNT

In these two examples, pointing data regardless of the receiver used, will be
put in the file JUNK.PNT.  If you want to restrict the plot to a particular
receiver, you must edit JUNK.PNT.  Each pointing observation is represented by
one line in the file.  The receiver name is included in that line.  The title
(first) line, the Model lines and the Offset lines are ignored by SHOW_POINT.
