/* ** ** 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 55973.596036 0.001195 5.28374 0.98490 0.94915 0 0.56365 0.09672 0.18278 0.03123 2.97818 0.21678 1.00211 0.07246 55973.597590 0.000359 3.05280 0.82777 0.94355 0 1.03694 0.24441 0.31912 0.07522 3.16556 0.42432 0.97524 0.13071 55973.598269 0.000321 6.98558 3.04469 0.94595 0 0.44597 0.18386 0.13661 0.05633 3.11534 0.44058 0.95397 0.13491 55973.599227 0.000637 7.39745 3.04914 0.94091 0 0.31054 0.11997 0.07229 0.02732 2.29720 0.33012 0.48179 0.06845 55973.600364 0.000501 5.10143 1.89658 0.91908 0 0.51638 0.17628 0.11940 0.03980 2.63427 0.38784 0.62119 0.08920 55973.601337 0.000472 6.85592 2.77085 0.93865 0 0.30820 0.11649 0.09475 0.03581 2.11298 0.30238 0.64784 0.09271 55973.602121 0.000312 5.11474 1.85714 0.98148 0 0.59560 0.19854 0.18212 0.06071 3.04636 0.43855 0.93016 0.13391 55973.602818 0.000385 7.10992 2.87135 0.93985 0 0.36508 0.13799 0.11219 0.04240 2.59566 0.36926 0.79715 0.11340 55973.604161 0.000958 11.17295 3.23224 0.94562 0 0.28446 0.07890 0.08710 0.02416 3.17823 0.26136 0.97506 0.08019 55973.605668 0.000550 6.82030 2.10673 0.95263 0 0.45512 0.13138 0.13896 0.04011 3.10404 0.34114 0.94798 0.10419
