NAME

       mTblSort - Sorts a table on numeric values

SYNOPSIS

       mTblSort [-d] in.tbl colname out.tbl

DESCRIPTION

       Sorts a table on numeric values.

OPTIONS

       -d     Turns on debugging

ARGUMENTS

       in.tbl Path to input table

       colname
              Name of column to sort on (column must contain numeric values)

       out.tbl
              Path to output table

RESULT

       [struct stat="OK", count=nrows]

       where nrows is the number of rows in the table.

MESSAGES

       OK     [struct stat="OK", count=nrows]

       ERROR  Cannot allocate memory for data

       ERROR  Cannot open input file

       ERROR  Cannot open output file

       ERROR  Table file open failed for [in.tbl]

       ERROR  Table file does not have fixed-length records

       ERROR  Table does not contain column [colname]

EXAMPLES

       $ mTblSort images.tbl ra ra_sorted.tbl
              [struct stat="OK", count=5, nmatches=3]

       ra_sorted.tbl is now sorted on the column "ra".

BUGS

       The drizzle algorithm has been implemented but has not been tested in this release.

       If  a  header  template  contains  carriage  returns  (i.e., created/modified on a Windows
       machine), the cfitsio library will be unable to read it properly, resulting in the  error:
       [struct stat="ERROR", status=207, msg="illegal character in keyword"]

       It  is  best  for the background correction algorithms if the area described in the header
       template completely encloses all of the input images in their entirety. If parts of  input
       images  are  "chopped  off"  by  the  header  template,  the background correction will be
       affected. We recommend you use an expanded header  for  the  reprojection  and  background
       modeling  steps, returning to the originally desired header size for the final coaddition.
       The default background matching assumes that there are no non-linear background variations
       in  the  individual  images  (and  therefore  in the overlap differences). If there is any
       uncertainty in this regard, it is safer to turn on the "level  only"  background  matching
       (the "-l" flag in mBgModel.
