/* ** ** 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 56038.376435 0.000900 0.27080 0.02208 0.99678 0 5.25700 0.19701 4.67731 0.17527 1.42361 0.10310 1.26730 0.09178 56038.378116 0.000781 0.33928 0.02813 0.97778 0 4.93633 0.20417 4.41535 0.18262 1.67481 0.12032 1.49797 0.10762 56038.379812 0.000914 0.29312 0.02375 0.99367 0 4.84946 0.18864 4.33214 0.16851 1.42146 0.10104 1.27049 0.09031 56038.381640 0.000914 0.29654 0.02423 0.98101 0 4.83221 0.18808 4.29965 0.16734 1.43295 0.10294 1.27569 0.09165 56038.383466 0.000911 0.31535 0.02561 0.97460 0 4.68137 0.18533 4.15645 0.16454 1.47628 0.10469 1.30968 0.09287 56038.385940 0.001562 0.32590 0.01969 0.97963 0 4.80852 0.14281 4.29348 0.12751 1.56708 0.08243 1.39882 0.07357
