/* ** ** 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 58319.050437 0.000553 0.14763 0.03585 0.96335 0 1.81445 0.15728 1.45663 0.12627 0.26787 0.06075 0.21502 0.04877 58319.051566 0.000576 0.15551 0.03958 0.98492 0 1.58368 0.14713 1.24804 0.11594 0.24629 0.05835 0.19415 0.04600 58319.052639 0.000498 0.14659 0.03561 0.97674 0 2.04635 0.17767 1.60377 0.13926 0.29997 0.06805 0.23550 0.05341 58319.053574 0.000437 0.16903 0.04211 0.98013 0 1.99735 0.19075 1.56193 0.14917 0.33761 0.07769 0.26392 0.06073 58319.054514 0.000503 0.12728 0.03070 1.00000 0 2.27602 0.18669 1.79456 0.14720 0.28968 0.06571 0.22738 0.05157 58319.055524 0.000506 0.18137 0.04535 0.95429 0 1.63914 0.16013 1.28893 0.12591 0.29729 0.06842 0.23389 0.05382 58319.056589 0.000558 0.15412 0.03763 0.96373 0 1.74471 0.15750 1.37984 0.12453 0.26890 0.06101 0.21271 0.04824 58319.057741 0.000593 0.13722 0.03316 0.96585 0 1.84655 0.15360 1.45777 0.12126 0.25339 0.05748 0.19981 0.04532 58319.059372 0.001039 0.14154 0.02559 0.96657 0 1.80425 0.11573 1.42468 0.09136 0.25538 0.04317 0.20207 0.03416
