make.data.array.maps: Make Data Stamps

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

Make Data Stamps

Description

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

Create a series of length (m) list of (n,n) arrays, containing the data cutouts around all input catalogue objects.

Usage

make.data.array.maps(outenv=parent.env(environment()),env=NULL)

Arguments

env	environment; the environment containing the parameters used in ‘measure.fluxes’
outenv	environment; the environment where the returned values are to be stored. If not provided, outenv defaults to the input env.

Details

This function creates cutouts of the input image, input mask, and error map. This is done so that parallelisation is as efficient as possible.

Value

numeric [[m]][n,n] list; stamps of the input image Further numeric [[m]][n,n] list may be generated, but are assigned to the output environment directly, and are not returned.
