/* ** ** 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 58224.206909 0.000310 0.24341 0.06251 0.98131 0 1.78883 0.20248 1.52026 0.17208 0.43542 0.10037 0.37152 0.08562 58224.207832 0.000613 0.32782 0.05357 0.97642 0 1.73382 0.14191 1.47712 0.12090 0.56838 0.08039 0.48390 0.06843 58224.208934 0.000489 0.36189 0.05997 0.98817 0 1.93150 0.16684 1.65741 0.14316 0.69899 0.09885 0.59980 0.08482 58224.209901 0.000477 0.35350 0.05832 0.98788 0 2.07468 0.17739 1.78041 0.15223 0.73341 0.10348 0.62937 0.08881 58224.210740 0.000362 0.23929 0.05973 0.97600 0 1.59922 0.17745 1.37243 0.15228 0.38268 0.08557 0.32842 0.07344 58224.211619 0.000518 0.38302 0.06378 0.96648 0 1.76852 0.15544 1.51306 0.13299 0.67738 0.09580 0.57900 0.08188 58224.212603 0.000466 0.39073 0.06601 0.98758 0 1.87453 0.17080 1.60289 0.14605 0.73243 0.10420 0.62666 0.08915 58224.213509 0.000440 0.46379 0.08044 0.96053 0 1.70550 0.16706 1.46367 0.14337 0.79099 0.11321 0.67883 0.09716 58224.214417 0.000469 0.39177 0.06579 0.97531 0 1.87566 0.16735 1.60958 0.14361 0.73482 0.10454 0.63062 0.08972 58224.215216 0.000330 0.24681 0.06045 0.97368 0 1.82977 0.20028 1.56990 0.17184 0.45160 0.09896 0.38754 0.08492 58224.216038 0.000492 0.38761 0.06553 0.99412 0 1.78361 0.16290 1.51996 0.13883 0.69134 0.09837 0.58958 0.08388 58224.216938 0.000408 0.42669 0.07293 0.97872 0 1.96142 0.18320 1.68316 0.15721 0.83692 0.11979 0.71819 0.10279 58224.218043 0.000697 0.33115 0.04629 0.95436 0 2.12046 0.14619 1.80975 0.12474 0.70220 0.08539 0.60052 0.07302
