La Serena Data Science School Project on finding periodic signals in CRTS quasar light curves

The scripts require gatspy (for fast Lomb-Scargle) and pyaov (for Analysis of Variance).

The code is built around the LightCurve object, which is instantiated from a three column data file (time, magnitude, magnitude error).

>>> from lightcurve import LightCurve
>>> lc = LightCurve("/my/lightcurve.dat") #the file containing the lightcurve
>>> lc.get_pbest()
Peak of    1.350E+02 at frequency       3.64061161304
