NAME


mMakeImg - Generate synthetic FITS images

SYNOPSIS


mMakeImg [-d level] [-n noise_level] [-b bg1 bg2 bg3 bg4] [-t tbl col width epoch mag]
template.hdr out.fits

DESCRIPTION


Generates synthetic FITS images, with varying levels of noise, from a table of provided
point sources. Each source is treated independently and its flux is distributed on a
source-specific point-spread function.

OPTIONS


-d level
Turns on debugging to the specified level (1-4).

-n noise_level
Specified random noise equal to noise_level will be added to image background.

-b bg1 bg2 bg3 bg4
Specifies the four corners for a 'tilted' background for the image. Each value is a
floating point number specifying the background height at the corner.

-t tbl col width epoch mag
Specifies a table of sources to be added to the raw image. tbl is the table
filename, col is the column name which contains the source fluxes, width is a
floating point number determining the point spread of each source, epoch is the
coordinate system reference year, and mag is the reference magnitude of the source
list. In addition, the source table should have ra and dec columns for the image
positions.

Several input tables can be specified if desired through repeated use of the -t
flag and arguments.

ARGUMENTS


template.hdr
FITS header template, used to indicate the desired parameters of the output image

out.fits
Path of FITS image to be generated.

RESULT


Synthetic FITS output image; sources in image will represent the values from the input
table(s).
