Installation & setup:

sedpy is pip installable:

.. code-block:: shell

	python -m pip install astro-sedpy

Or you can install the latest version from github:

.. code-block:: shell

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

Then in python, e.g.,

.. code-block:: python

	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.

.. _filter_list: sedpy/data/filters/README.md .. _docs: docs/transmissions.rst

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 <https://github.com/blanton144/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 <https://dust-extinction.readthedocs.io/en/stable/>_ instead.
