Asteroid lightcurves


A lightcurve is useful to measure precisely the rotation period of an asteroid
My 1st lightcurves have been obtained with a home made program, written with IRAF
and could perform automatic measures on a moving object.
I currently perform photometry with 'Teleauto'

EPHEMERIDES software

My 1st measures have been done with a SBIG ST4.
I currently use an Audine Kaf401e.
My instruments are a Vixen GP200 (200/800) and the T400 of the Observatory of Nice (400/5000)

To find the period, you can use'Curvexpert'.
but the best way remains 'Courbrot', that performs the Fast Fourier Transform of the signal.
