Abstract:
The period changes of 86 M5 RR Lyrae stars have been investigated on a
100-yr time base. The published observations have been supplemented by
archival Asiago, Konkoly and Las Campanas photographic observations
obtained between 1952 and 1993.
Description:
In this paper we publish the photographic observations obtained with
the University of Toronto 61-cm telescope at the Las Campanas
Observatory of the Carnegie Institution of Washington between 1972 and
1991, with the 60-cm reflector of the Konkoly Observatory at Budapest
during the years 1952-1963, with the 1-m RCC telescope of the
Konkoly Observatory at Piszkesteto Mountain Station from 1976 to
1993 and with the 1.2-m reflector of the Asiago Observatory of
University of Padova in 1971.

Note (1): R1 remark flag as follows:
0 = linear fit to the O-C
1 = quadratic fit to the O-C
2 = third-order fit to the O-C
- = higher-order or multiple fit to the O-C
: = denotes stars with scarce O-C data
Note (2): R2 remark flag, complexity index of the O-C diagram, as follows:
0 = straight line or parabola
1 = low-order fit with scatter or third-order fit
2 = higher-order or multiple fit of irregular character
Note (3): This column refers only to RRab stars as follows:
Bl = Blazhko effect
d = deficient photometry for the investigation of light-curve variability
