DESCRIPTION
TBKEYCOL takes a list of ST tables \fItable\fR and copies the values of the
header keywords \fIkeywords\fR into newly created columns of the same name.
If the input file is not an ST table, an output column of the same name as the
keyword already exists, or the keyword does not exist, no action is
taken. Otherwise a new column of the same name as the keyword is created,
and the value of the keyword is copied into all rows of the table.
.ih
EXAMPLES
1. For the list of ST tables in tablelist, copy the values of the header
keywords "IMAGE", "ITIME", "IFILTER", and "XAIRMASS" into table columns
of the same name.
.nf
pt> tbkeycol @tablelist "IMAGE,ITIME,IFILTER,XAIRMASS"

TIME REQUIREMENTS

BUGS

write permission on the table in order to run TBKEYCOL.
