Lightcurve file schema

The HATNet lightcurves are provided as gzipped CSV files. There is a small Python module available to read these files (you will need Numpy and PyFITS installed).

Each lightcurve file has a header describing its contents. Here's an example header for the lightcurve file for HAT-P-7:

# HAT-154-0001553 - 2MASS J19285935+4758102
# RA = 292.247 deg, DEC = 47.970 deg
# V = 10.25, R = 10.05, I = 9.85, J = 9.55, H = 9.34, K = 9.33
#
# Total LC detections: 27034
# HAT stations: HN06, HN07, HN08, HN09
#
# Filters used:
#
# 29 - r - SDSS r SN404 AST0166
# 20 - R - Bessel R (Omega Optical)
# 26 - r - SDSS r SN401 AST0166
# 9 - I - Bessel I (Omega Optical)
