/* ** ** Swift/XRT hardness ratio for Cen A. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 56127.121622 0.000726 11.70549 3.04575 0.97610 0 0.16822 0.04206 0.13757 0.03439 1.96914 0.14194 1.60796 0.11589 56127.123060 0.000712 15.19292 4.44469 0.96341 0 0.13633 0.03867 0.11051 0.03135 2.07122 0.14802 1.67941 0.12002 56127.124493 0.000720 8.03595 1.81661 0.96787 0 0.25376 0.05442 0.20542 0.04406 2.03919 0.14573 1.65154 0.11803 56127.126504 0.001291 7.56565 1.28029 0.96256 0 0.24453 0.03902 0.19834 0.03165 1.85000 0.10425 1.50068 0.08457 56127.327516 0.000425 3.48958 1.26077 0.95238 0 0.55172 0.18208 0.16287 0.05150 1.92526 0.28306 0.71848 0.10228 56127.328346 0.000405 9.85638 4.63409 0.94286 0 0.22764 0.10198 0.07826 0.03500 2.24374 0.32009 0.75370 0.10736 56127.329258 0.000506 23.74707 17.12287 0.90857 0 0.08150 0.05763 0.02619 0.01852 1.93543 0.27306 0.63831 0.09001
