/* ** ** 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 58675.078151 0.000385 0.16726 0.04038 0.96241 0 2.21543 0.20150 1.86930 0.17001 0.37055 0.08286 0.31302 0.06999 58675.078976 0.000440 0.14786 0.03600 0.96053 0 2.14832 0.18956 1.83200 0.16165 0.31765 0.07209 0.27084 0.06147 58675.079749 0.000333 0.21513 0.05054 0.96522 0 2.16109 0.21330 1.84295 0.18190 0.46491 0.09912 0.39706 0.08465 58675.080377 0.000295 0.22723 0.05721 1.00000 0 2.00681 0.21869 1.70714 0.18600 0.45600 0.10349 0.38767 0.08799 58675.081245 0.000573 0.10100 0.02371 0.96465 0 2.43132 0.17338 2.07627 0.14806 0.24556 0.05491 0.20977 0.04691 58675.082165 0.000347 0.20440 0.05024 0.95000 0 2.02205 0.20634 1.71675 0.17515 0.41330 0.09242 0.35146 0.07859 58675.082830 0.000318 0.26020 0.06555 0.96364 0 1.74103 0.19885 1.48730 0.16987 0.45302 0.10171 0.38700 0.08689 58675.083930 0.000781 0.13243 0.02500 0.97454 0 2.18582 0.14223 1.86705 0.12148 0.28946 0.05131 0.24726 0.04383
