/* ** ** 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 57960.911971 0.000304 0.17735 0.04438 0.96190 0 2.57085 0.24949 2.16965 0.21058 0.45593 0.10516 0.38592 0.08903 57960.912639 0.000365 0.13472 0.03316 0.96825 0 2.79312 0.23869 2.36163 0.20183 0.37630 0.08685 0.31949 0.07371 57960.913296 0.000292 0.18634 0.04612 1.00000 0 2.48698 0.24442 2.10176 0.20654 0.46343 0.10526 0.39131 0.08887 57960.914014 0.000425 0.10859 0.02557 0.97279 0 3.02157 0.22280 2.58265 0.19043 0.32811 0.07337 0.28019 0.06265 57960.914763 0.000324 0.22042 0.05218 0.99107 0 2.11867 0.21789 1.79576 0.18468 0.46701 0.09957 0.39706 0.08465 57960.915796 0.000709 0.19049 0.02978 0.97959 0 2.54565 0.15967 2.16738 0.13593 0.48492 0.06944 0.41283 0.05911 57960.917000 0.000495 0.10797 0.02577 0.95906 0 2.61053 0.19199 2.23192 0.16414 0.28187 0.06401 0.24099 0.05473 57960.917810 0.000315 0.19184 0.04678 0.96330 0 2.33998 0.22753 1.99316 0.19380 0.44890 0.10038 0.38159 0.08533 57960.918559 0.000434 0.13004 0.03103 0.99333 0 2.41969 0.20129 2.06714 0.17196 0.31467 0.07036 0.26890 0.06013 57960.919378 0.000385 0.15624 0.03627 0.94737 0 2.58654 0.21835 2.21096 0.18664 0.40412 0.08738 0.34547 0.07470 57960.920165 0.000396 0.13561 0.03327 0.96350 0 2.56252 0.21421 2.18014 0.18224 0.34751 0.08016 0.29529 0.06812 57960.920906 0.000344 0.18109 0.04416 0.98319 0 2.21194 0.21532 1.89105 0.18408 0.40055 0.08957 0.34245 0.07657 57960.922069 0.000819 0.13197 0.02333 0.97880 0 2.36489 0.14527 2.01156 0.12356 0.31209 0.05174 0.26563 0.04404
