TELASSAR : Two dimEnsionaL spectrAl analysiS for muSe And xshooteR

A clunky, hideous package for doing what I want and upsetting every real programmer in our galactic quadrant. Brute force and ignorance are the tools of my trade. Nothing much beyond visualisation for (pseudo)long-slit spectra, with new functionalities to be added when I figure out how!

Basic Bits

Can generate WCS information for a 2D slice either from a FITS file directly, or from a custom data array + header. No promises, though. At the very least it makes an attempt!

Usage

from telassar import PVSlice
my_file = PVSlice(filename='some_file.fits')

or

my_file = PVSlice(data=my_data, header=my_header)

A 2D slice can also be reduced to a 1D spatial or spectral profile given a wavelength range and offset range:

new_file = my_file.spatial_profile(arc=[0, 30], wave=[6725, 6730], spat_unit=True, spec_unit=True)

For quick data viewing, a contour plot is easily generated:

my_file.plot_contours()

Some further customization can be done with the plots; check out the notebook in the examples folder for a better idea.

Features

Not a lot here at the moment, but a few things are being included:

• Registering/unregistering skyline emissions;

======= TODO

• Add LMFit-py modeling options for fitting profiles
• Expand spatial/spectral profile class functionality (ie plotting, fitting, and integration)
• Learn how to do everything properly.
