VizieR Online Data Catalog: Microlensing optical depth & event rates from MOA-II (Sumi+, 2016)
Abstract
We use the same data set as Sumi+ (2013, J/ApJ/778/150), which used the data taken in the 2006 and 2007 seasons by the MOA-II survey, with the 1.8m MOA-II telescope located at the Mt. John University Observatory, New Zealand. The centers of the 22 Galactic bulge (GB) fields of the MOA-II survey are listed in Table 1. The images were taken using the custom MOA-Red wide-band filter, which is equivalent to the sum of the standard Kron/Cousins R and I bands. Each field is divided into 80 subfields and each subfield is individually calibrated using the red clump giant (RCG) feature in each subfield CMD more precisely. The number of subfields used in the final analysis is 1536 in total and also given in Table 1 for each field. The coordinates and other properties of the subfields are listed in Table 4.
The OGLE (Udalski 2003AcA....53..291U) also conducts a microlensing survey toward the GB with the 1.3m Warsaw telescope at the Las Campanas Observatory in Chile. The median seeing is about 1.3 arcsec. Most observations are taken in the standard Kron-Cousin I band with occasional observations in the Johnson V band. (1 data file).- Publication:
