Light curve format and software

The HATSouth light curves are provided as gzipped CSV files. You can read these with a small Python module (hatlc.py), which is self-contained and requires only the numpy package. To use this, you can download the Python file directly into your work directory, or install the astrobase package, which comes with additional light curve tools.

To read the light curve:

# if you have the hatlc.py module in your current directory or PYTHONPATH
>>> import hatlc

# or if you're using astrobase
>>> from astrobase.hatsurveys import hatlc

# read in a light curve file to a Python dict
>>> lcd = hatlc.read_csvlc('/path/to/HATS-XXb-hatlc.csv.gz')

# look at the columns, object information, and metadata
>>> hatlc.describe(lcd)

# get times, mags, and errs from columns and read into numpy arrays
>>> times, mags, errs = lcd['rjd'], lcd['atf_000'], lcd['aie_000']

Each light curve file has a header describing its contents. Here's an example header for the light curve file for HATS-23b:
