NAME

prenumber -- renumber an APPHOT/DAOPHOT database

USAGE

renumber infile

PARAMETERS

infile
The APPHOT/DAOPHOT database to be renumbered.
id = "ID"
The name of the keyword whose value is the sequence number of the object
idoffset = 0
An integer offset to be added to the id numbers of the stars in the output renumbered photometry file. If idoffset is > 0, the output id numbers will run from 1 + idoffset to N + idoffset instead of from 1 to N. in the database.

DESCRIPTION

PRENUMBER is a simple task which accepts an APPHOT/DAOPHOT database file and renumbers the objects in the file from 1 + idoffset to N + idoffset, where N is the number of objects in the database. A renumber operation is often performed after an append operation to insure that the database objects have unique id numbers or after a sort to put the id numbers in order.

PRENUMBER is a script which executes TXRENUMBER if the APPHOT/DAOPHOT database is a text database or TCALC if the file is an STSDAS table database.

EXAMPLES

1. Renumber a sorted NSTAR database that has been sorted on magnitude.

   pt> prenumber m92r.nst.1

2. Renumber a PHOT photometry file of extra stars so as to ensure the stars' id numbers are greater than 4000.

    pt> prenumber m92r.mag.extra idoffset=4000
