astro-sedpy 0.2.0

Simple tools for astronomical spectral energy distributions, particularly filter projections.

Modules for storing and operating on astronomical source spectral energy distributions.

Installation & setup:

git clone https://github.com/bd-j/sedpy
cd sedpy
pip install .

Then in python, e.g.,

from sedpy import observate
# get magnitude from a spectrum:
filt = observate.Filter("sdss_r0")
mag = filt.ab_mag(angstroms, f_lambda_cgs)
# or get several magnitudes at once
filterlist = observate.load_filters(["galex_NUV", "sdss_r0"])
mags = observate.getSED(angstroms, f_lambda_cgs, filterlist=filters)

see the FAQ

Description:

• observate has methods for generating synthetic photometry through any filters, and classes for dealing with filters generally. There is some functionality for spectra (vaccum to air conversions). With a huge debt to Mike Blanton’s kcorrect code .
• attenuation contains simple dust attenuation methods.
• extinction (Deprecated) classes for a detailed modeling of extinction curves, following the Fitzpatrick & Massa parameterizations. See dust_extinction instead.
• photometer (Deprecated) has some basic aperture photometry algorithms. See photutils instead.
• ds9region (Deprecated) has some simple ds9 region classes.
• modelgrid (Deprecated) is a module with classes for the storage and interpolation of model SEDs. Largely superceded by scipy.interpolate algorithms.
