/* ** ** 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 56040.122742 0.000781 0.28026 0.02288 0.97778 0 6.19174 0.23382 5.31501 0.20071 1.73530 0.12558 1.49005 0.10782 56040.124319 0.000796 0.29807 0.02436 0.97818 0 5.73821 0.22327 4.93274 0.19193 1.71036 0.12295 1.47010 0.10568 56040.125856 0.000741 0.31311 0.02576 0.97656 0 5.89343 0.23528 5.06448 0.20218 1.84532 0.13274 1.58568 0.11407 56040.127456 0.000859 0.27248 0.02203 0.96633 0 5.88959 0.21788 5.05681 0.18707 1.60478 0.11536 1.37790 0.09905 56040.129160 0.000845 0.28025 0.02283 0.97603 0 5.75861 0.21748 4.95030 0.18695 1.61384 0.11648 1.38729 0.10013 56040.130748 0.000744 0.33620 0.02792 0.98444 0 5.41133 0.22510 4.64897 0.19338 1.81927 0.13078 1.56307 0.11236 56040.132392 0.000900 0.31759 0.02345 0.98714 0 5.85147 0.21230 5.03200 0.18257 1.85839 0.11951 1.59823 0.10278
