error happens when

import extinction

No module named 'extinction_plot'

Hi @kbarbary,

Would it be possible to implement different units for the wavelength to calculate the extinction?

In the v0.4.6 release, all wheels build successfully except for the MacOS wheel on CPython 3.10, which failed with this error.

@kboone any ideas?

Any plans to include the SMC bar extinction curve from Gordon et al 2003? Would be super helpful for high-z work.

When I make a numpy array of integers, I get a ValueError. It would be nice to be able to use integers as wavelengths. I don't speak Cython - is this an easy thing to implement?

Here is the call:
extinction.ccm89(np.array([2000]), 1, 3.1)

And the error:

ValueError Traceback (most recent call last)
in ()
----> 1 extinction.ccm89(np.array([2000]), 1, 3.1)

extinction.pyx in extinction.ccm89 (extinction.c:3133)()

ValueError: Buffer dtype mismatch, expected 'double' but got 'long'

Thanks for creating this helpful Python package, so that I don't have to go code up all those equations!! This code is very helpful in a project I am working on, and I would like to be able to cite it.

Would you consider making a release to Zenodo to get a DOI, so that it could be easily cited in a paper?

I am using this module for some features in a package/paper (https://github.com/nikhil-sarin/redback), so Is there a specific way to acknowledge this module? Is there a paper I am supposed to cite?

Hello!

I have a simple doubt: Do I have to deredshift a spectra from observer frame in order to use these extinction models?

Thank you!

For whatever reason, on a clean image I cannot pip install extinction. MWE

$ docker run --rm -ti python bash
/# pip install extinction

I had opened #14 because I thought pyproject.toml was simply missing the build-backend key, but I've realized that any local install of the package will work. I tried the following all with success

$ pip install git+https://github.com/kbarbary/extinction#egg=extinction
$ git clone https://github.com/kbarbary/extinction && pip install extinction/
$ echo 'build-backend = "setuptools.build_meta"\n' >> extinction/pyproject.toml && pip install extinction/

I followed the guide on the documentation, but an error occurred.

AttributeError Traceback (most recent call last)

AttributeError: module 'extinction' has no attribute 'remove'

It appears that extinction only works with 1-d wavelength inputs.

Example:

import extinction
import numpy as np
a = extinction.fitzpatrick99(
    wave=np.random.uniform(3800., 10000., (1000, 10, 10)), r_v=3.1, a_v=1.)

Hey there,

I am trying to install extinction in order to use MOSFIT for some SNe LC work.

Via pip3 install for 0.45 install dies on OSX 11.3.0 and 11.3.1 after attempting several deprecated versions of extinction under Python 3.9.5. (via homebrew) This is even with the clang compiler set to x86_64 target and homebrew working in x86_64 mode

Am happy to help you guys diagnose this and even try to help solve it if I can (and hey, I need it =p ), so lemme know what additional information I might provide to help run this down and solve it.

I've attached logs to the message in case that helps to figure out the problem.

thanks!
Daryl.

(note: it installs on POP OS 21.04 pre-release fine under Python 3.9.4 so imagine this is an OSX only thing - though I did have to wrestle mpi4py on 21.04 to also be installed.).
