/* ** ** 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 57897.940391 0.000425 0.21922 0.05582 0.93878 0 2.42967 0.26254 1.28478 0.13880 0.53264 0.12280 0.28280 0.06514 57897.941215 0.000399 0.21625 0.05449 0.96377 0 2.55227 0.27957 1.38979 0.15213 0.55193 0.12524 0.29734 0.06748 57897.941994 0.000379 0.21669 0.05549 0.98473 0 2.62947 0.29366 1.39237 0.15542 0.56978 0.13129 0.30253 0.06968 57897.942954 0.000582 0.13207 0.03287 0.97512 0 2.77843 0.23744 1.49053 0.12738 0.36696 0.08578 0.19646 0.04594 57897.943973 0.000437 0.20087 0.04947 0.96689 0 2.54822 0.26295 1.36656 0.14099 0.51186 0.11446 0.27443 0.06136 57897.944829 0.000420 0.25197 0.06328 0.99310 0 2.08590 0.23493 1.12926 0.12719 0.52557 0.11798 0.28493 0.06396 57897.946227 0.000978 0.09834 0.02316 0.97929 0 2.35206 0.16832 1.26460 0.09049 0.23131 0.05190 0.12396 0.02782 57897.947989 0.000784 0.11420 0.02699 0.97048 0 2.45630 0.18766 1.32987 0.10160 0.28051 0.06273 0.15234 0.03407 57897.949719 0.000946 0.15861 0.02780 0.98471 0 2.75323 0.18261 1.49549 0.09919 0.43669 0.07084 0.23642 0.03835
