VizieR Online Data Catalog: OGLE II SMC RR Lyrae stars (Soszynski+, 2002)
Abstract
Observations of the SMC were collected between June 26, 1997 and November 25, 2000. Eleven driftscan fields (SMCSC1-SMCSC11) covering about 2.4 square degrees of central parts of the SMC were observed. The majority of frames were taken in the I photometric band (about 280-340 epochs depending on the field). Other images were collected through the V-band (typically about 30 epochs) and B-band (about 20 epochs) filters. The effective exposure time lasted 125, 174 and 237 seconds for the I , V and B-band, respectively. Themedian seeing was about 1.3" for our dataset.
