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.
