Abstract:
We present here the sixth list of light maxima of RR Lyrae stars from
the GEOS RR Lyr Survey, a GEOS program (http://www.upv.es/geos/)
(Boninsegna et al., 2002ASPC..259..166B 2002ASPC..259..166B) of automated observations of
RR Lyr stars started in January 2004.
Description:
The present list contains 587 maxima observed with no filter between
July and December 2006 (Table 1). The maxima are determined by fitting
a polynomial function on the data points. The uncertainties on
individual maxima are estimated from the data sampling of each
maximum. The nominal sampling (two consecutive 30-s exposures taken
every 10 minutes on a time baseline of 2 hours centered around the
predicted maximum time) may be altered by local events (weather or
telescope operation). This results uncertainties from 0.002 to 0.010
day. For a well observed star, the mean uncertainty on maxima is about
0.003-day (4.3-minutes). The O-C's are computed with the GCVS elements
(Kholopov et al., 1985, See Cat. II/250).
