Kombine

Multiple-frames are composed to a single image.

Command

munipack kombine [..] files

Description

Purpose of this routine is compound images to get more deeper exposure, to increase the dynamic range or to create of a mosaics.

Result image can be scaled to arbitrary size, rotated and shifted. Also photometric information can be saved on per-image base.

The routine provides sub-pixel resolution. The blurring of image due to convolution is not reduced by the implemented algorithm.

Prerequisites

Needs both astrometry and photometry.

Input And Output

On input, list of frames containing both astrometric and photometric information is expected.

On output, a new FITS frame is created.

Parameters

Optional parameters:

-i
interpolation method: none,bilinear,bicubic (default)
--adjust
adjust sky level of individual exposures
--expomask
use exposure mask to normalise photon rates

Geometry parameters:

-p
projection: none, gnomonic (default)
--xcen, --ycen
centre of projection on chip [pix] (default: width/2, height/2)
--rcen, --dcen
centre of projection in Right Ascension and Declination [deg]
--scale
scale [pix/deg]
--angle
positional angle [deg]

See Common options for input/output filenames.
