Gallagher III University of Wisconsin - Madison N ------------------------------------------------------------------------------------ Abstract We request deep observations of 2 representative fields in the Small Magellanic Cloud with Chandra and HST, with the primary goal of measuring the luminosity function and space density of X-ray binaries and other sources down to an unprecedented faint luminosity limit of 2x10E32 erg/s. This will be the faintest XLF ever obtained for any galaxy, including our own. HST photometry to 24th magnitude in V and I filters will identify the sources and provide Fx/Fopt, which will be vital in quantifying the LMXB population and in measuring the properties of the first coronally active stars ever detected in an external galaxy. ------------------------------------------------------------------------------------ 10766( 5) - 08/15/07 16:35 - [ 2] Observations Description ------------------------ This is a substitute program for the original ACS program. We obtain V (F606W) and I (F814W) WFPC2 exposures in the central part of our Deep Chandra SMC fierlds. Because of the smaller area coverage of WFPC2 the fields are adjusted to cover regions with high density of X-ray sources. The total integration is 2400s in each band. the observations are obtained with a 3pt dither pattern, in order to reject cosmic rays and obtain some sub-pixel sampling.
