/* ** ** 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 55368.781666 0.000402 0.21111 0.03302 0.97122 0 4.34893 0.28064 3.53334 0.22800 0.91810 0.13083 0.74522 0.10619 55368.782421 0.000353 0.20811 0.03271 0.96721 0 4.88400 0.31744 4.03454 0.26222 1.01641 0.14545 0.84002 0.12021 55368.783162 0.000388 0.22238 0.03552 0.97761 0 4.07902 0.27497 3.36465 0.22681 0.90709 0.13136 0.74870 0.10843 55368.783934 0.000385 0.20146 0.03225 0.96241 0 4.53600 0.29165 3.76282 0.24193 0.91384 0.13395 0.75809 0.11112 55368.784695 0.000376 0.22794 0.03605 0.96154 0 4.19591 0.28251 3.48074 0.23436 0.95644 0.13687 0.79298 0.11348 55368.785436 0.000365 0.26831 0.04298 0.97619 0 3.63843 0.26799 3.01980 0.22243 0.97624 0.13888 0.81012 0.11525 55368.786226 0.000425 0.21531 0.03377 0.97279 0 3.92327 0.25928 3.23975 0.21409 0.84474 0.12017 0.69682 0.09913 55368.787134 0.000483 0.16683 0.02563 0.97605 0 4.44048 0.25749 3.66201 0.21235 0.74081 0.10539 0.61132 0.08697 55368.788037 0.000420 0.20530 0.03205 0.97931 0 4.14012 0.26621 3.42061 0.21989 0.84996 0.12092 0.70172 0.09983 55368.788980 0.000524 0.16550 0.02524 0.95580 0 4.22326 0.24104 3.49879 0.19969 0.69895 0.09885 0.57900 0.08188 55368.789877 0.000373 0.28383 0.04582 0.96899 0 3.39209 0.25896 2.80682 0.21427 0.96279 0.13696 0.79716 0.11340 55368.790748 0.000498 0.17390 0.02678 0.97093 0 4.15708 0.24491 3.43389 0.20229 0.72291 0.10284 0.59668 0.08488 55368.791666 0.000420 0.19658 0.03170 0.97241 0 4.20368 0.27432 3.48103 0.22716 0.82635 0.12186 0.68449 0.10094 55368.792539 0.000454 0.18171 0.02791 0.96178 0 4.40355 0.26419 3.64934 0.21894 0.80018 0.11316 0.66336 0.09381 55368.793717 0.000723 0.16993 0.02131 0.97600 0 4.37322 0.20757 3.63350 0.17246 0.74315 0.08625 0.61757 0.07167
