Description:
astrosedpy 0.3.2
Modules for storing and operating on astronomical source spectral energy distributions.
Installation & setup:
sedpy is pip installable:
python -m pip install astro-sedpy
Or you can install the latest version from github:
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)
For the filters available by default see the filter_list.
For adding transmission curves, see these docs.
This code can be referenced as:
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.
smoothing methods for smoothing well-sampled spectra.
extinction (Deprecated) classes for a detailed modeling of extinction curves,
following the Fitzpatrick & Massa parameterizations.
See dust_extinction instead.
