write.fits.image.file: Write FITS Image to File

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

Write FITS Image to File

Description

Write an input image to file, using the standard FITS format.

Usage

write.fits.image.file(filename, image, header_in, xsize = NA,
ysize = NA, xcent = NA, ycent = NA, pixeloffset = NA,
nochange = FALSE, verbose = FALSE, diagnostic = FALSE)
make.fits.header(hdr)

Arguments

filename	string; The path to, and filename of, the output image
image	numeric (p,q) array; the image to be output
header_in	list; a FITS header, usually a duplicate of the original header that the new image was derived from.
xsize	numeric; The new x-axis length to be written to the fits header (pixels). Only used if nochange == FALSE
ysize	numeric; The new y-axis size to be written to the fits header (pixels). Only used if nochange == FALSE
xcent	numeric; The new reference pixel for the x-axis, to be written to the fits header (pixel). Only used if nochange == FALSE
ycent	numeric; The new reference pixel for the y-axis, to be written to the fits header (pixel). Only used if nochange == FALSE
pixeloffset	numeric; The magnitude of the offset between the original pixel location paramters (from header_in), and what we wish to output.
nochange	logical; if TRUE, the new image will be output with the header_in header. Otherwise, new values will be added as above.
diagnostic	logical; if TRUE, then perform diagnostic checks and outputs
verbose	logical; if TRUE, then perform verbose outputs
hdr	data.frame; In the form of a fits header, this will be converted to a string which can be output as a binary fits header

Value

NULL; Output is to file character; fits header to be written to file
