To read the 'bst' files and stack appropriate scans
star (req) (i) (0) (is)
infile (key) (i)
Listing to read. Default is BST file for that star.
outext (key) (i)
Set this keyword to write output FITS files. If not set equal
to an extension, default is BU1. (Thus, /outext writes files
with .BU1 extension; outext='test' writes files with .test)
bkgnd (opt) (i)
Background subtraction option. 1=use background vectors from
raw data file (default). 2=use backgrounds from table.
0=no background subtraction.
istack (key) (i) (0,1) (i)
EXACT stack number(s) to process. Stack numbers start with 1.
iscan (key) (i) (0,1) (i)
Stack(s) which include the scan number(s) given via ISCAN will be
sstack (key) (i) (0) (i)
Starting stack number. All stacks beginning with stack SSTACK
will be processed.
sscan (key) (i) (0) (i)
All stacks beginning with the stack containing scan SSCAN will
nstacks (key) (i) (0) (i)
Number of stacks to process. This keyword may be used with the
SSTACK or SSCAN keywords, but NOT with ISTACK or ISCAN.
inspect (key) (i) (0) (i)
If set, the user will be able to screen individual scans.
batch (key) (i)
If set, no plots will appear on the screen and the user will
not be prompted or allowed to reject portions of scans. A
postscript file of the results will be generated. Without
this keyword, the user has the option of writing a postscript
file after viewing the plot on the screen.
Process all stacks for star 22 in batch mode, creating output files:
Process stacks 30, 31, and 32 in star 22, writing output FITS files:
Process stacks 30, 40, and 50 in star 22, writing output FITS files:
Process those stacks that contain scans 500 and 600, no FITS files:
Process the stack containing scan 500 and all subsequent stacks:
stk_read Reads BST file
within Range checking
stack Stacks the scans
BST listing file
Input raw data file (STACK)
Temperature and/or background correction files (STACK)
Output stacked spectral file(s) and/or postscript files (STACK)
*SYSTEM VARIABLES USED:
The scan numbers are read from the listing (BST) file. Then, the
input raw file name is constructed using the star number. A list of
output file names is constructed using the star number and an image
sequence number (1 through the number of stacks). The stacks are
determined on the basis of zeroes located in the listing file. If
the ISTACK, ISCAN, or NSTACKS keywords are set, the list of stacks
is modified accordingly. Then STACK is called for each stack.

26 Jul 95 LLT fixed some things and added sscan and sstack
29 Feb 96 RWT use either '.bu1 or '.uu1' extension depending on value
01 May 96 RWT use !copr system variable for disk location
