This is intended to house utilities for coadding and using COS data. It is forked from Nico Nell's python port of Charles Danforth's IDL code (the latter of which had many other contributors, too, most notably Brain Keeney but also myself, to a small degree) Relevant websites: https://casa.colorado.edu/~danforth/science/cos/costools.html https://casa.colorado.edu/~nell/python-coaddx1d/ https://github.com/cosmonaut/python-coaddx1d Nico Nell's original README is preserved below: ## python-coaddx1d This is a python translation of Charles Danforth's coaddx1d IDL routine. This program provides the same capabilities as the IDL coaddx1d routine. The coaddition provides three save file formats of dat csv and a python pickle file (the equivalent of idl save files -- that is, the ability to save the python spectrum object). There are also two convenient plotting routines for easy creation of plots of the entire coadded spectrum. ## Intsallation Dependencies: python >= 2.5 numpy scipy pyfits idlsave matplotlib Installation is simple and accomplished by the command: python setup.py install Alternatively for installing in a different location one can use: python setup.py --root="/some/directory" install ## Usage API documentation and examples are located at http://casa.colorado.edu/~nell/site/software/python-coaddx1d.html
