/* ** ** 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 57428.455672 0.000654 5.65860 2.18877 0.95556 1 0.18581 0.06678 0.08079 0.02904 1.05140 0.15028 0.46055 0.06582 57428.456688 0.000363 48.98649 49.47656 1.00000 1 0.03656 0.03656 0.01667 0.01667 1.79099 0.25397 0.79804 0.11315 57428.457473 0.000421 5.96132 2.44823 1.00000 1 0.25462 0.09807 0.11462 0.04414 1.51788 0.21635 0.68458 0.09758 57428.458243 0.000349 6.90403 4.24658 1.00000 1 0.12051 0.06958 0.05455 0.03149 0.83203 0.17649 0.37720 0.08001 57428.458998 0.000407 23.61714 17.02636 1.00000 1 0.06720 0.04752 0.03077 0.02176 1.58708 0.22282 0.72682 0.10204 57428.459957 0.000552 14.46482 8.59961 0.97368 1 0.08288 0.04785 0.03750 0.02165 1.19887 0.16999 0.53922 0.07646 57428.461075 0.000566 17.03201 11.55457 0.92306 1 0.07180 0.04761 0.03169 0.02101 1.22297 0.17525 0.54875 0.07863 57428.462208 0.000566 6.57672 2.74759 0.97436 1 0.17778 0.06979 0.07947 0.03119 1.16918 0.16709 0.52115 0.07448 57428.463210 0.000436 6.77769 2.83171 0.96667 1 0.22445 0.08809 0.10007 0.03928 1.52125 0.21799 0.68119 0.09761 57428.464140 0.000494 5.84687 2.39780 1.00000 1 0.22641 0.08718 0.10189 0.03924 1.32377 0.18682 0.59567 0.08405 57428.465157 0.000523 7.73915 3.41322 0.97222 1 0.16317 0.06808 0.07347 0.03066 1.26278 0.18049 0.56582 0.08086 57428.466115 0.000436 9.51465 4.68435 0.96667 1 0.16262 0.07669 0.07315 0.03450 1.54726 0.21889 0.69668 0.09856 57428.466943 0.000392 5.45003 2.27639 1.00000 1 0.30091 0.11814 0.13509 0.05303 1.63999 0.23376 0.73529 0.10480 57428.467873 0.000537 11.72292 6.28504 0.97297 1 0.10457 0.05403 0.04700 0.02429 1.22590 0.17566 0.54874 0.07863 57428.469253 0.000842 5.78880 1.78432 0.96090 1 0.21310 0.06096 0.09533 0.02726 1.23358 0.14158 0.55278 0.06344
