The main point here is to do some checking to make sure that the index values match. There are allot of ways to stuff two files together, but some of these files are massive and have had quite a bit of processing done on them. There is absolutely no guarantee that they will match up, or that the index key will always be in the same column. The value of the index needs to be checked for each pair of rows to make sure that matching data is merged in the output.
Can anybody help me out with this problem

funindex
funindex(1) SAORD Documentation funindex(1)NAME
funindex - create an index for a column of a FITS binary table
SYNOPSIS
funindex <switches> <iname> [oname]
OPTIONS
NB: these options are not compatible with Funtools processing. Please
use the defaults instead.
-c # compress output using gzip"
-a # ASCII output, ignore -c (default: FITS table)"
-f # FITS table output (default: FITS table)"
-l # long output, i.e. with key value(s) (default: long)"
-s # short output, i.e. no key value(s) (default: long)"
DESCRIPTION
The funindex script creates an index for the specified column (key) by running funtable -s (sort) and then saving the column value and the
record number for each sorted row. This index will be used automatically
by funtools filtering of that column, provided the index file's modification date is later than that of the data file.
The first required argument is the name of the FITS binary table to index. Please note that text files cannot be indexed at this time. The
second required argument is the column (key) name to index. While multiple keys can be specified in principle, the funtools index process-
ing assume a single key and will not recognize files containing multiple keys.
By default, the output index file name is [root]_[key].idx, where [root] is the root of the input file. Funtools looks for this specific
file name when deciding whether to use an index for faster filtering. Therefore, the optional third argument (output file name) should not
be used for funtools processing.
For example, to create an index on column Y for a given FITS file, use:
funindex foo.fits Y
This will generate an index named foo_y.idx, which will be used by funtools for filters involving the Y column.
