Description
We present reliable, serendipitous x-ray detections found in three
different deep ACIS imaging fields in two different energy bandpasses.
We ran the Chandra X-ray Center's exttt{cell detect} source detection
program on a ``soft band'' image (from 0.5 - 2.0 keV) and a ``hard
band'' image (from 2.0 - 7.0 keV). The 3 high latitude fields
investigated as part of the Chandra Multiwavelength Project (ChaMP)
include: MS 1137.5+6625, the second most distant cluster of galaxies in
the Einstein Extended Medium Sensitivity Survey (EMSS) at a redshift of
0.78; CL 0848.6+4453, a field containing three galaxy clusters at 0.6
< z < 1.3 (including the highest-redshift non-AGN cluster); and A
0620-00, a short-period black hole x-ray nova (BHXN). The integration
times for each field are 120 ks, 190 ks, and 45 ks, respectively. We
discuss the optimum set of cell detect parameters and present
preliminary analyses such as hardness ratios and log N - log S plots.
