man mTblSort (1): 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.
