Fit photometric phase curves of asteroids.

Features - Install - Documentation

Features

Observe the phase curve of an asteroid, ...

>>> from phunk import PhaseCurve
>>> # Observations of (20) Massalia from Gehrels 1956
>>> phase = [0.57, 1.09, 3.20, 10.99, 14.69, 20.42]
>>> mag = [6.555, 6.646, 6.793, 7.130, 7.210, 7.414]
>>> pc = PhaseCurve(phase=phase, mag=mag)

..., fit it in one of multiple photometric models, ....

>>> pc.fit(["HG", "HG1G2", "sHG1G2"])

..., and plot / process the results.

>>> pc.HG1G2.H
>>> pc.HG12.H
>>> pc.plot()

Provide a target to PhaseCurve to have phunk compute the required ephemerides for you.

>>> epoch = [35193, 35194, 35198, 35214, 35223, 35242]  # in MJD
>>> pc = PhaseCurve(epoch=epoch, mag=mag, target='massalia')
>>> pc.fit(['sHG1G2'])  # phunk computes required RA, Dec, and phase at epoch of observation
>>> pc.sHG1G2.H
