/* ** ** 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 59646.206323 0.000605 0.28890 0.02408 0.99043 0 7.70070 0.30175 6.48312 0.25403 2.22475 0.16365 1.87549 0.13796 59646.207593 0.000666 0.25940 0.02100 0.99565 0 7.84407 0.28832 6.63620 0.24392 2.03475 0.14674 1.72247 0.12421 59646.208796 0.000538 0.33183 0.02739 0.97849 0 7.74327 0.31692 6.58128 0.26936 2.56949 0.18421 2.18399 0.15657 59646.209960 0.000625 0.28650 0.02334 1.00000 0 7.58771 0.29271 6.43921 0.24840 2.17388 0.15596 1.84469 0.13234 59646.211172 0.000587 0.27973 0.02271 0.99507 0 8.25919 0.31522 7.01763 0.26784 2.31030 0.16551 1.96297 0.14063 59646.212405 0.000645 0.28307 0.02310 0.99103 0 7.41827 0.28348 6.30496 0.24093 2.09990 0.15143 1.78483 0.12871 59646.213649 0.000599 0.28422 0.02307 1.00000 0 7.95039 0.30669 6.75765 0.26068 2.25968 0.16136 1.92056 0.13714 59646.214844 0.000596 0.26440 0.02141 0.96602 0 8.81758 0.32467 7.49684 0.27604 2.33135 0.16812 1.98214 0.14294 59646.216045 0.000605 0.31032 0.02481 0.99522 0 7.63540 0.29839 6.49985 0.25401 2.36938 0.16526 2.01694 0.14068
