/* ** ** 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 58609.176832 0.000535 0.32252 0.05351 0.97838 0 1.99838 0.16400 1.68694 0.13844 0.64451 0.09293 0.54418 0.07844 58609.177746 0.000379 0.46708 0.08082 0.98473 0 1.94776 0.19169 1.64856 0.16225 0.90976 0.12948 0.77217 0.10990 58609.178678 0.000547 0.31290 0.05244 0.98942 0 2.01054 0.16732 1.68851 0.14053 0.62910 0.09151 0.52850 0.07685 58609.179760 0.000535 0.35110 0.05883 0.97297 0 1.83807 0.15692 1.55938 0.13311 0.64535 0.09305 0.54720 0.07888 58609.180773 0.000477 0.40233 0.06823 0.96970 0 1.83061 0.16625 1.53463 0.13938 0.73651 0.10549 0.61908 0.08867 58609.181734 0.000483 0.36598 0.06123 0.98204 0 1.96321 0.17263 1.65843 0.14584 0.71850 0.10226 0.60738 0.08644 58609.182787 0.000570 0.33050 0.05304 0.97491 0 1.96757 0.16057 1.65755 0.13528 0.65028 0.08986 0.54994 0.07599 58609.241502 0.000472 0.38945 0.06601 0.99387 0 1.84690 0.16726 1.57196 0.14234 0.71928 0.10304 0.61140 0.08758 58609.242419 0.000446 0.36170 0.06043 0.97403 0 2.13806 0.18711 1.83813 0.16085 0.77334 0.11007 0.66404 0.09451 58609.243296 0.000431 0.40027 0.06737 1.00000 0 1.97658 0.18199 1.70372 0.15686 0.79117 0.11148 0.68194 0.09609 58609.244300 0.000573 0.33422 0.05579 0.98485 0 1.75297 0.14752 1.51117 0.12717 0.58588 0.08447 0.50506 0.07281 58609.245698 0.000825 0.38053 0.04921 0.98246 0 1.82038 0.12447 1.56204 0.10679 0.69271 0.07604 0.59384 0.06518
