/* ** ** Swift/XRT hardness ratio for 3C 273. ** 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 58167.410133 0.000446 0.52886 0.09357 0.98701 0 1.45220 0.15291 1.23867 0.13042 0.76801 0.10920 0.65583 0.09325 58167.411077 0.000498 0.32632 0.05376 0.97674 0 2.11710 0.17332 1.81067 0.14823 0.69086 0.09877 0.59052 0.08442 58167.412075 0.000501 0.39070 0.06588 0.98266 0 1.75245 0.15888 1.50100 0.13608 0.68469 0.09735 0.58639 0.08338 58167.412885 0.000310 0.24567 0.06013 0.99065 0 1.89525 0.21007 1.61605 0.17912 0.46560 0.10161 0.39689 0.08661 58167.413675 0.000480 0.36165 0.06077 1.00000 0 1.94013 0.17131 1.65240 0.14590 0.70164 0.10031 0.59763 0.08543 58167.414586 0.000431 0.41786 0.07044 0.97987 0 1.91853 0.17597 1.63594 0.15005 0.80168 0.11338 0.68607 0.09703 58167.415454 0.000437 0.48544 0.08534 0.99338 0 1.60839 0.16622 1.37023 0.14157 0.78078 0.11103 0.66458 0.09449 58167.416337 0.000446 0.41408 0.06915 0.98701 0 1.93118 0.17761 1.64687 0.15146 0.79966 0.11147 0.68219 0.09509 58167.417092 0.000310 0.20962 0.05175 0.97196 0 2.15539 0.22556 1.84073 0.19260 0.45182 0.10104 0.38526 0.08615 58167.417763 0.000362 0.53022 0.09399 0.98400 0 1.78439 0.18892 1.52923 0.16191 0.94612 0.13452 0.81046 0.11523 58167.418426 0.000301 0.21161 0.05229 0.97115 0 2.22303 0.23380 1.88522 0.19828 0.47041 0.10519 0.39670 0.08870 58167.419083 0.000356 0.50311 0.08929 0.99187 0 1.88169 0.19592 1.61020 0.16765 0.94669 0.13606 0.80923 0.11631 58167.420116 0.000677 0.37161 0.05426 0.97436 0 1.80954 0.13776 1.54314 0.11748 0.67244 0.08379 0.57360 0.07148
