/* ** ** Swift/XRT hardness ratio for Mrk 501. ** 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 59013.089856 0.000564 0.22518 0.03552 0.97436 0 2.71036 0.18463 2.33473 0.15904 0.61033 0.08683 0.52441 0.07461 59013.090987 0.000561 0.23479 0.03690 0.95876 0 2.70155 0.18826 2.32457 0.16197 0.63431 0.08935 0.54646 0.07697 59013.091849 0.000301 0.15311 0.03704 0.97115 0 2.98617 0.27562 2.59094 0.23914 0.45722 0.10224 0.39670 0.08870 59013.092709 0.000558 0.22261 0.03505 0.96891 0 2.75785 0.18590 2.39289 0.16130 0.61393 0.08734 0.53283 0.07581 59013.093846 0.000579 0.20198 0.03120 0.96000 0 3.01985 0.19164 2.62169 0.16637 0.60995 0.08591 0.52938 0.07456 59013.095035 0.000611 0.18919 0.02941 0.97156 0 2.97429 0.18607 2.57355 0.16099 0.56270 0.08006 0.48604 0.06915 59013.096326 0.000680 0.17407 0.02702 0.97447 0 2.87804 0.17292 2.48622 0.14937 0.50098 0.07171 0.43280 0.06194 59013.097445 0.000434 0.27333 0.04413 0.96000 0 2.92718 0.21874 2.51954 0.18827 0.80009 0.11451 0.68826 0.09851 59013.098583 0.000703 0.23844 0.03295 0.97942 0 2.66680 0.16461 2.32090 0.14325 0.63586 0.07862 0.55333 0.06842
