/* ** ** 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 57436.896135 0.000363 0.60552 0.17275 1.00000 1 2.48731 0.43503 0.52572 0.09194 1.50610 0.33945 0.31772 0.07159 57436.896919 0.000421 0.38943 0.10294 0.93103 1 3.49016 0.48222 0.75308 0.10404 1.35916 0.30628 0.29419 0.06629 57436.897660 0.000320 0.54563 0.15211 0.95455 1 3.21785 0.53566 0.69662 0.11596 1.75576 0.39262 0.38096 0.08518 57436.898445 0.000436 0.34982 0.09115 0.93333 1 3.75671 0.49163 0.80987 0.10598 1.31416 0.29612 0.28368 0.06392 57436.899461 0.000581 0.35893 0.09364 0.95000 1 2.72248 0.36583 0.58648 0.07880 0.97719 0.21851 0.21053 0.04708 57436.900711 0.000668 0.36717 0.09513 0.97826 1 2.34489 0.32153 0.50367 0.06906 0.86098 0.18927 0.18540 0.04075 57436.901931 0.000552 0.29728 0.07607 0.94737 1 3.41457 0.41387 0.74133 0.08984 1.01509 0.22877 0.22064 0.04972 57436.902846 0.000363 0.53838 0.15085 0.96000 1 2.86444 0.48360 0.61865 0.10444 1.54216 0.34484 0.33334 0.07454 57436.903616 0.000407 0.58555 0.16718 0.96429 1 2.31662 0.40089 0.49948 0.08644 1.35649 0.30803 0.29207 0.06632 57436.904487 0.000465 0.71998 0.17999 0.90625 1 2.43950 0.39020 0.52763 0.08439 1.75639 0.33746 0.38031 0.07307 57436.905460 0.000508 0.49957 0.13848 1.00000 1 2.11674 0.34164 0.45547 0.07351 1.05747 0.23832 0.22694 0.05114 57436.906274 0.000305 1.06642 0.35090 1.00000 1 1.64948 0.39552 0.35430 0.08495 1.75904 0.39636 0.37824 0.08523 57436.907102 0.000523 0.59452 0.15044 0.97558 1 2.27060 0.35298 0.49077 0.07628 1.34992 0.26954 0.29125 0.05814
