/* ** ** 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 56493.805243 0.000298 0.50008 0.04510 1.00000 0 8.59286 0.44747 7.56433 0.39394 4.29709 0.31640 3.78217 0.27856 56493.805871 0.000330 0.44967 0.03913 1.00000 0 8.74186 0.42387 7.75687 0.37607 3.93091 0.28407 3.48483 0.25186 56493.806522 0.000321 0.46089 0.04033 1.00000 0 8.79210 0.42843 7.80034 0.38002 4.05222 0.29452 3.59982 0.26162 56493.807101 0.000258 0.57105 0.05171 1.00000 0 8.78210 0.48031 7.76986 0.42493 5.01504 0.36189 4.43949 0.32036 56493.807671 0.000312 0.46163 0.04048 0.99074 0 8.92791 0.43823 7.96573 0.39100 4.12138 0.29950 3.67537 0.26703 56493.808324 0.000341 0.45398 0.04106 0.98305 0 8.13694 0.40274 7.25457 0.35903 3.69404 0.27968 3.29449 0.24939 56493.808993 0.000327 0.46969 0.04086 1.00000 0 8.43343 0.41809 7.52341 0.37299 3.96109 0.28316 3.53070 0.25241 56493.809667 0.000347 0.49540 0.04343 0.98333 0 7.68414 0.38662 6.82577 0.34341 3.80672 0.27328 3.38239 0.24282 56493.810327 0.000312 0.45345 0.03996 0.99074 0 9.08253 0.44616 8.06122 0.39597 4.11843 0.30131 3.65807 0.26759 56493.810946 0.000307 0.45956 0.04085 1.00000 0 9.03680 0.44844 8.04551 0.39916 4.15299 0.30629 3.69546 0.27255 56493.811536 0.000284 0.57040 0.05055 0.99010 0 8.58492 0.45947 7.49886 0.40135 4.89684 0.34593 4.28014 0.30233 56493.871863 0.000799 0.45323 0.03961 0.95290 0 8.04246 0.39145 3.30817 0.15935 3.64510 0.26461 1.49939 0.10795 56493.873336 0.000674 0.48413 0.04248 0.97854 0 8.08154 0.40525 3.57935 0.17943 3.91250 0.28170 1.72956 0.12452 56493.874702 0.000692 0.47922 0.04149 0.96234 0 8.05550 0.39491 3.60375 0.17665 3.86032 0.27548 1.72827 0.12331 56493.876930 0.001536 0.42210 0.02612 0.96422 0 7.89592 0.26558 3.50271 0.11780 3.33288 0.17313 1.47696 0.07672
