/* ** ** 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 58601.209452 0.000388 0.45671 0.07814 0.97015 0 1.99670 0.19227 1.68914 0.16264 0.91190 0.12897 0.77051 0.10897 58601.210303 0.000463 0.35607 0.05973 0.98125 0 2.12827 0.18466 1.78590 0.15494 0.75781 0.10880 0.63659 0.09140 58601.211136 0.000370 0.64712 0.11976 0.99219 0 1.44488 0.17090 1.21340 0.14356 0.93501 0.13308 0.78433 0.11163 58601.211970 0.000463 0.35259 0.05883 0.97500 0 2.15011 0.18719 1.81212 0.15773 0.75810 0.10792 0.63853 0.09088 58601.212847 0.000414 0.49106 0.08553 0.93706 0 1.79725 0.17816 1.50721 0.14941 0.88255 0.12640 0.73921 0.10588 58601.213718 0.000457 0.36388 0.06182 0.97468 0 2.09562 0.18523 1.74661 0.15438 0.76255 0.11064 0.63598 0.09227 58601.214617 0.000443 0.39236 0.06718 0.94771 0 2.05089 0.18650 1.72052 0.15645 0.80468 0.11674 0.67545 0.09800 58601.215500 0.000440 0.40370 0.06816 0.98684 0 1.97749 0.17961 1.64719 0.14960 0.79831 0.11361 0.66407 0.09451 58601.216446 0.000506 0.31589 0.05172 0.96571 0 2.23325 0.18079 1.87126 0.15148 0.70547 0.10040 0.58941 0.08389 58601.217386 0.000434 0.48677 0.08517 0.98000 0 1.66431 0.16932 1.39082 0.14152 0.81014 0.11532 0.67762 0.09644 58601.218252 0.000431 0.47465 0.08259 0.96644 0 1.75252 0.17542 1.45626 0.14578 0.83183 0.11840 0.69174 0.09845 58601.219395 0.000712 0.45014 0.05618 0.97967 0 2.09489 0.14838 1.76381 0.12492 0.94299 0.09689 0.79339 0.08151
