/* ** ** 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 58611.988992 0.000747 0.07775 0.01812 0.97287 0 2.58122 0.16272 2.09519 0.13206 0.20070 0.04504 0.16353 0.03669 58611.990111 0.000373 0.16136 0.03953 0.96899 0 2.38685 0.22059 1.96166 0.18129 0.38515 0.08738 0.31644 0.07179 58611.990971 0.000486 0.13710 0.03325 0.95833 0 2.17732 0.18650 1.79093 0.15341 0.29851 0.06773 0.24568 0.05574 58611.991816 0.000359 0.18645 0.04629 0.95968 0 2.17116 0.21895 1.78267 0.17977 0.40480 0.09184 0.33239 0.07541 58611.992698 0.000524 0.15553 0.03795 0.93923 0 1.82164 0.16359 1.49610 0.13435 0.28331 0.06428 0.23267 0.05279 58611.993673 0.000451 0.17538 0.04207 0.94231 0 1.96324 0.18213 1.61251 0.14959 0.34431 0.07618 0.28271 0.06255 58611.994463 0.000339 0.17222 0.04355 0.96581 0 2.41141 0.23325 1.97985 0.19150 0.41530 0.09704 0.34097 0.07967 58611.995299 0.000498 0.12719 0.03154 0.97093 0 2.20615 0.18317 1.81418 0.15063 0.28060 0.06557 0.23072 0.05391 58611.996205 0.000408 0.14728 0.03696 0.98582 0 2.30018 0.21059 1.88688 0.17274 0.33878 0.07915 0.27719 0.06477 58611.997120 0.000506 0.12759 0.03032 0.97714 0 2.27713 0.18276 1.84110 0.14775 0.29055 0.06497 0.23431 0.05239 58611.998014 0.000388 0.14401 0.03500 0.97761 0 2.55034 0.22245 2.09653 0.18287 0.36727 0.08332 0.30194 0.06850 58611.999177 0.000775 0.12446 0.02394 0.95522 0 2.35081 0.15107 1.93209 0.12416 0.29259 0.05304 0.24059 0.04362
