astromulti 1.0.6

A set of functions for analysis of astronomical images

astromulti

This is a collection of modules for complementing AstroPy in astronomy analysis

fits_actions: various analysis/modification routines for FITS images

• cutout_fits: make cutouts of 2D/3D FITS files

• remove_axes_34: removes degenerate 3rd and 4th axes

• bg_filter_I: filter out background emission using 'un-sharp masking' method developed by Sofue & Reich (1979)

• bg_filter_QU: modified version of bg_filter_I to work for polarization data as well (-ve values)

• convert_to_JyPerBeam: convert a FITS file to Jy/beam units (original units in Kelvin)

• regioncut: get a cutout of a region

• TTdata: get pixel values of two FITS files with same WCS (for temperature-temperature plots)

• measure_FD: measure flux density of a region in a fits file

• smooth_fits: convolve a FITS image to a larger beam size

• smooth_fits_to_commonbeam: convolve two FITS images to a common beam size

• gauss2Dfit_fits: perform 2D Gaussian fitting on a point source

linear_fitting: do least squares fitting to get a line or a plane

new_colormap: make a new colormap that can be used in plotting data

region_meta: meta details of a region

simple_funcs: a collection of simple functions

As the license states, no liability will be accepted. Whatever tests I ran are on Linux, and for my own use case.
