/* ** ** 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 54952.760114 0.000043 0.30817 0.13417 0.97520 0 4.68614 1.01260 3.11013 0.67205 1.44411 0.54582 0.95844 0.36226 54952.760682 0.000508 0.36024 0.09427 0.97143 1 2.99129 0.39832 0.64821 0.08631 1.07758 0.24276 0.23363 0.05264 54952.761903 0.000712 0.48346 0.08253 0.97959 1 4.17488 0.41080 0.89132 0.08770 2.01841 0.28156 0.43098 0.06012 54952.763036 0.000421 0.31364 0.07900 0.96552 1 4.40396 0.54170 0.95110 0.11699 1.38125 0.30361 0.29799 0.06550 54952.763864 0.000407 0.43971 0.11769 0.85714 1 3.50433 0.49661 0.74719 0.10588 1.54089 0.34988 0.32863 0.07461 54952.764662 0.000392 0.40545 0.10842 0.92593 1 3.64325 0.51474 0.77810 0.10993 1.47716 0.33538 0.31548 0.07163 54952.765534 0.000479 0.28852 0.07247 1.00000 1 4.10851 0.49935 0.87560 0.10642 1.18537 0.26057 0.25284 0.05557 54952.766449 0.000436 0.41780 0.09525 0.96667 1 4.29567 0.54777 0.92288 0.11768 1.79471 0.33917 0.38621 0.07299 54952.767321 0.000436 0.29707 0.07614 1.00000 1 4.28395 0.52813 0.91636 0.11297 1.27264 0.28594 0.27247 0.06122 54952.768236 0.000479 0.33470 0.08254 0.96970 1 3.83266 0.47502 0.81971 0.10160 1.28281 0.27350 0.27500 0.05863 54952.769064 0.000349 0.47624 0.13134 0.95833 1 3.35007 0.52448 0.72062 0.11282 1.59545 0.36222 0.34292 0.07785 54952.769746 0.000334 0.52895 0.14746 0.95652 1 3.19755 0.52497 0.68321 0.11217 1.69134 0.38105 0.36107 0.08135 54952.770836 0.000755 0.59259 0.10970 0.97774 1 3.01754 0.35198 0.64604 0.07536 1.78816 0.25704 0.38328 0.05509
