/* ** ** Swift/XRT hardness ratio for Mrk 421. ** 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 59964.218077 0.000362 0.25873 0.00933 1.00000 0 67.74179 1.10978 61.51189 1.00765 17.52712 0.56334 15.91082 0.51133 59964.218789 0.000350 0.26601 0.00972 1.00000 0 68.61672 1.14437 61.19807 1.02064 18.25251 0.59381 16.27382 0.52941 59964.219503 0.000365 0.25462 0.00924 1.00000 0 68.57967 1.12133 61.69791 1.00868 17.46178 0.56570 15.69896 0.50862 59964.220229 0.000362 0.25639 0.00928 1.00000 0 69.64254 1.13483 62.10094 1.01190 17.85549 0.57675 15.92071 0.51419 59964.220962 0.000370 0.24225 0.00869 1.00000 0 71.97263 1.14167 64.19417 1.01822 17.43503 0.56121 15.54635 0.50036 59964.221786 0.000454 0.25575 0.00827 0.99614 0 69.36316 1.01705 61.54427 0.90241 17.73942 0.51122 15.73995 0.45360 59964.334496 0.000168 0.23169 0.01971 1.00000 0 51.41074 1.85665 29.14190 1.03480 11.91145 0.91734 6.66908 0.50284 59964.334847 0.000182 0.23094 0.01524 1.00000 0 55.95787 1.58829 41.47083 1.17675 12.92308 0.76961 9.57719 0.57039 59964.335162 0.000133 0.23392 0.01783 1.00000 0 57.90349 1.93821 41.08029 1.37477 13.54458 0.92742 9.64611 0.66057 59964.335428 0.000133 0.23860 0.01885 1.00000 0 56.30587 1.97958 37.05612 1.30279 13.43461 0.95053 8.84935 0.62602 59964.335720 0.000159 0.22283 0.01814 1.00000 0 50.07867 1.73922 31.97785 1.11065 11.15883 0.82183 7.12779 0.52493 59964.336027 0.000148 0.25187 0.02038 1.00000 0 49.07955 1.79980 30.79019 1.12914 12.36152 0.89146 7.74994 0.55889 59964.336343 0.000168 0.23283 0.01880 1.00000 0 46.64830 1.64849 29.08601 1.02769 10.86116 0.78869 6.78346 0.49243 59964.336678 0.000168 0.22795 0.01861 1.00000 0 47.07443 1.65409 29.73938 1.04490 10.73079 0.79058 6.75911 0.49778 59964.337005 0.000159 0.23803 0.01946 0.98182 0 48.26988 1.72255 30.30476 1.08125 11.48955 0.84508 7.21904 0.53101 59964.337335 0.000171 0.22601 0.01840 0.98305 0 48.11233 1.67806 29.75153 1.03765 10.87371 0.79976 6.72117 0.49439 59964.337659 0.000153 0.23252 0.01940 1.00000 0 50.18447 1.80028 31.20444 1.11940 11.66901 0.87900 7.25672 0.54662 59964.337960 0.000148 0.24572 0.02015 1.00000 0 50.13023 1.83962 31.26244 1.14712 12.31800 0.90357 7.68297 0.56362 59964.338244 0.000136 0.28324 0.02408 1.00000 0 45.75463 1.79845 29.05613 1.14212 12.95975 0.97719 8.22993 0.62053 59964.338634 0.000255 0.24916 0.01541 1.00000 0 49.24614 1.37622 30.91891 0.86401 12.27029 0.67681 7.70804 0.42521
