read.fitsim: Read FITS Image

In astro: Astronomy Functions, Tools and Routines

Description

The mid-level function 'read.fitsim' allows FITS images to be read directly into R.

Usage

read.fitsim(file, hdu = 1, maxlines = 50000, xlo = NA, xhi = NA, 
            ylo = NA, yhi = NA)

Arguments

file	file name
hdu	header and data unit to be read
maxlines	maximum number of header lines
xlo	lower x pixel sub-region (image only)
xhi	upper x pixel sub-region (image only)
ylo	lower y pixel sub-region (image only)
yhi	upper y pixel sub-region (image only)

Details

The mid-level function 'read.fitsim' is a wrapper around 'read.fits', and provides a more simplistic output of that routine.

Value

A matrix of data corresponding to the original FITS image.
