Figure 1. Light curve measurements of several RR Lyrae
variables are shown in this figure. These variables were selected for
observation based on data taken from the Sloan Digital Sky Survey
commissioning runs 94 (done on 19 Sep 98) and 259 (done on 17 Nov
98). These RR Lyrae stars were searched for in the SDSS data by Beth
Willmann and Scott Anderson. In addition to having been observed by
the SDSS and at MRO, these variables have also been observed in the
LOENEOS data base. In the figure X marks denote LOENEOS data and +
marks denote MRO data.
Further
details about these observations may be found on Kevin's web
pages.
