dustapprox 0.1

A tool for computing extinction coefficients in a quick and dirty manner

This is a set of tools to compute photometric extinction coefficients in a quick and dirty way.

full documentation at: http://mfouesneau.github.io/dustapprox/

Quick Start

import pandas as pd
from dustapprox import models
from dustapprox.literature import edr3
import pylab as plt

# get Gaia models
lib = models.PrecomputedModel()
r = lib.find(passband='Gaia')[0]  # taking the first one
model = lib.load_model(r, passband='GAIA_GAIA3.G')

# get some data
data = pd.read_csv('models/precomputed/kurucs_gaiaedr3_small_a0_grid.csv')
df = data[(data['passband'] == 'GAIA_GAIA3.G') & (data['A0'] > 0)]

# values
kg_pred = model.predict(df)
