/* ** ** 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 59634.643481 0.000935 0.27867 0.02263 0.97833 0 7.93008 0.30144 4.47750 0.17007 2.20988 0.15854 1.25481 0.08990 59634.644913 0.000498 0.25769 0.03214 0.97093 0 7.33931 0.42187 3.79880 0.21829 1.89130 0.20935 0.98946 0.10946 59634.645741 0.000330 0.22498 0.03436 0.97368 0 8.59369 0.56642 4.33053 0.28540 1.93342 0.26636 0.97405 0.13417 59634.647029 0.000958 0.27957 0.02257 0.98792 0 8.06935 0.30636 4.37450 0.16601 2.25591 0.16076 1.22191 0.08703 59634.648840 0.000854 0.30188 0.02485 0.97966 0 8.27072 0.32814 4.51639 0.17915 2.49673 0.18008 1.36489 0.09842 59634.651233 0.001539 0.22635 0.01531 0.97556 0 8.66355 0.25137 4.64774 0.13477 1.96097 0.11982 1.05338 0.06430
