/* ** ** 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 55208.831778 0.000906 0.45084 0.03864 0.97125 0 3.97700 0.18871 2.91340 0.13820 1.79298 0.12799 1.31093 0.09355 55208.833549 0.000865 0.48258 0.04163 0.95318 0 3.97834 0.19364 2.89402 0.14086 1.91986 0.13676 1.39676 0.09949 55208.835346 0.000932 0.42541 0.03627 0.97826 0 4.11004 0.19126 2.96119 0.13779 1.74844 0.12491 1.26044 0.09005 55208.837065 0.000787 0.49850 0.04356 0.97794 0 4.12440 0.20742 2.99253 0.15049 2.05602 0.14691 1.49263 0.10663 55208.838613 0.000761 0.50510 0.04420 0.97338 0 4.26915 0.21571 3.06967 0.15510 2.15635 0.15405 1.55093 0.11080 55208.840297 0.000923 0.43073 0.03686 0.96865 0 4.14514 0.19531 2.98245 0.14051 1.78543 0.12756 1.28492 0.09179 55208.842146 0.000926 0.48749 0.03997 0.98185 0 4.11350 0.19349 2.93952 0.13827 2.00528 0.13466 1.43253 0.09619 55208.901657 0.000645 0.56024 0.04975 0.97758 0 3.76786 0.20021 3.26457 0.17346 2.11091 0.15017 1.82816 0.13005 55208.903014 0.000712 0.48800 0.04247 0.97967 0 3.92586 0.19618 3.38673 0.16923 1.91581 0.13650 1.65148 0.11766 55208.904490 0.000764 0.45317 0.03892 0.98106 0 3.94405 0.18889 3.39808 0.16273 1.78731 0.12740 1.54033 0.10980 55208.905922 0.000668 0.49394 0.04357 0.99134 0 4.03619 0.20622 3.48515 0.17806 1.99363 0.14334 1.72408 0.12396 55208.907326 0.000735 0.43402 0.03714 0.97638 0 4.30195 0.20249 3.68824 0.17358 1.86712 0.13343 1.60057 0.11438 55208.908770 0.000709 0.52681 0.04637 0.95918 0 3.71497 0.19083 3.20546 0.16465 1.95710 0.13986 1.68911 0.12071 55208.910624 0.001146 0.48743 0.03306 0.97222 0 4.01875 0.15584 3.48569 0.13516 1.95888 0.10900 1.69812 0.09448
