read.astr: Read Astrometry

In AngusWright/LAMBDAR: Measure galaxy fluxes from an arbitrary FITS image using input aperture locations and dimensions

Read Astrometry

Description

Read the header of a provided FITS file, and return the astrometry associated with that file.

Usage

read.astrometry(fitsname,hdu=1)

Arguments

fitsname	string; relative path and filename of the FITS file to be analysed.
hdu	integer; fits extension number

Details

This procedure is designed to read all common astrometry keywords. Nonetheless, the source should be checked to ensure that your fits file keywords are included.

Value

list; contains all keywords needed for determining locations in the fits image using astrometry.
