make.aperture.map: Create a Full Mask

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

Create a Full Mask

Description

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

Create a full image mask of all smaller masks/apertures which are input. The full mask is of dimension fullmaskdim. Pixel locations for the placement of smaller masks on large mask are determined from the input variables x, y.

Usage

make.aperture.map(outenv=parent.env(environment()),
masks, fullmaskdim, env=NULL, subs=NULL)

Arguments

outenv	environment; the environment where the returned values are to be stored. If not provided, outenv defaults to the input env.
masks	numeric length(m) list of (n,n) arrays; length (m) list of (n,n) stamps, each containing an aperture mask.
fullmaskdim	numeric (2) vector; fullmaskdim[1] is the x-dimension of the full mask. fullmaskdim[2] is the y-dimension. fullmaskdim values must be > submask width.
env	environment; the environment containing the parameters used in ‘measure.fluxes’
subs	numeric length(k) vector; the subset of apertures to add to the image. Default NULL is treated as 1:length(m).

Value

array; full mask, with dimensions fullmaskdim, of smaller masks placed in their appropriate locations.
