plotfits: Plot FITS images

In astro: Astronomy Functions, Tools and Routines

Description

This function allows a FITS image to be converted into a PNG/X11 image, or output as a data array for use within a function. 3 colour RGB images may also be constructed by using multiple file inputs.

Usage

plotfits(input, hdu = 1, func = "atan", slide = c(0,0,0), 
         scale = c(500,300,100), locut = 0, hicut = pi/2, invert = FALSE, 
         method = 1, type = "x11", width = 5, height = 5, units = "in", 
         res = 300, cen = c(NA,NA), xdim = NA, ydim = NA, 
         file = "image.png")

Arguments

input	input file(s)
hdu	input hdu
func	scaling function for plot [lin/log/atan]
slide	offset counts from the origin by a given value
scale	scaling value for each image
locut	lower cut (black)
hicut	upper cut (white)
invert	invert the output greyscale/colours
method	counts -> image conversion method [1/2]
type	output type [dat/png/eps/pdf/x11 or bitmap types]
width	output width
height	output height
units	output units
res	output resolution
cen	centre of image
xdim	x width (pixels)
ydim	y width (pixels)
file	output file name
