/* ** ** 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 55649.084101 0.000469 0.13809 0.01055 1.00000 0 19.28799 0.51360 17.75255 0.47268 2.66340 0.19079 2.45110 0.17559 55649.084975 0.000405 0.15581 0.01194 1.00000 0 19.96510 0.56664 18.30056 0.51938 3.11067 0.22139 2.84909 0.20277 55649.085822 0.000443 0.14474 0.01113 0.99346 0 19.55536 0.53189 18.05830 0.49117 2.83040 0.20355 2.61373 0.18797 55649.086664 0.000399 0.16841 0.01301 0.98551 0 18.95752 0.55613 17.42866 0.51127 3.19263 0.22812 2.93442 0.20967 55649.087501 0.000437 0.14314 0.01110 0.99338 0 19.95772 0.53991 18.42846 0.49854 2.85684 0.20760 2.63800 0.19169 55649.088325 0.000388 0.16825 0.01312 1.00000 0 18.98477 0.56412 17.53264 0.52097 3.19421 0.23032 2.94987 0.21270 55649.089219 0.000506 0.12905 0.00989 0.98857 0 19.27769 0.49372 17.80383 0.45597 2.48786 0.17962 2.29766 0.16588 55649.090177 0.000451 0.14166 0.01081 0.98718 0 19.80773 0.53060 18.29309 0.49002 2.80601 0.20050 2.59144 0.18516 55649.091045 0.000417 0.15043 0.01173 0.97917 0 20.28345 0.56528 18.56792 0.51748 3.05129 0.22227 2.79218 0.20343 55649.091907 0.000446 0.14545 0.01142 0.98701 0 19.09463 0.52616 17.63557 0.48596 2.77737 0.20423 2.56513 0.18862 55649.092830 0.000477 0.13822 0.01068 0.97576 0 19.22157 0.50992 17.68392 0.46912 2.65675 0.19287 2.44403 0.17738 55649.093745 0.000437 0.15215 0.01177 0.98675 0 18.87885 0.53059 17.43570 0.49003 2.87248 0.20712 2.65291 0.19128 55649.094636 0.000454 0.14286 0.01106 0.98726 0 19.44742 0.52785 17.96073 0.48750 2.77820 0.20135 2.56583 0.18596 55649.095808 0.000718 0.14636 0.00887 0.99597 0 19.23189 0.41555 17.76254 0.38380 2.81471 0.15929 2.59964 0.14712
