/* ** ** 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 59737.060711 0.000767 0.23549 0.01888 0.98491 0 7.15174 0.25058 6.42202 0.22502 1.68416 0.12145 1.51072 0.10894 59737.062103 0.000625 0.29283 0.02388 0.99074 0 7.14127 0.27960 6.34548 0.24843 2.09116 0.14958 1.86038 0.13306 59737.063431 0.000703 0.24981 0.02032 0.96708 0 7.53635 0.27124 6.65024 0.23935 1.88265 0.13731 1.66238 0.12124 59737.064719 0.000584 0.28403 0.02331 1.00000 0 7.75057 0.30088 6.84920 0.26588 2.20141 0.15921 1.94747 0.14083 59737.066339 0.001036 0.26359 0.01761 0.96957 0 7.11509 0.21841 6.34919 0.19491 1.87550 0.11128 1.67324 0.09927 59737.127436 0.000810 0.21303 0.01680 0.99643 0 7.45552 0.24792 6.68937 0.22243 1.58826 0.11361 1.42274 0.10176 59737.129053 0.000807 0.25345 0.01925 0.98925 0 7.21622 0.24664 6.47457 0.22129 1.82896 0.12409 1.64013 0.11122
