read.image: Read Input Images

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

Read Input Images

Description

__This function is not designed to be called directly, but rather is an internal function to measure.fluxes__

Read the FITS images (data, error map, mask map, and/or weight map) that are input to the procedure measure.fluxes. The procedure opens the files that are listed in the measure.fluxes parameter file, and generate the relevant default images in the event that one is not specified.

Usage

read.images(outenv=parent.env(environment()),
quiet=FALSE, showtime=FALSE, env=NULL)

Arguments

env	environment; the environment containing the parameters used in ‘measure.fluxes’
quiet	logical; if TRUE, all output is suppressed
showtime	logical; if TRUE, execution times are printed along with output
outenv	environment; the environment where the returned values are to be stored. If not provided, outenv defaults to the input env.

Value

NULL; the procedure outputs images into the ‘outenv’ environment, for use by ‘measure.fluxes’. These images/objects may include:

im	2D array containing the fits image data
imm	2D array containing the mask for the data image
ime	2D array containing the error map for the data image
imwt	2D array containing the weight map for the data image
data.hdr	List containing the FITS header information for the data image
mask.hdr	List containing the FITS header information for the mask image
error.hdr	List containing the FITS header information for the error map image
