/* ** ** 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 55535.523465 0.000417 0.14016 0.01071 0.97917 0 22.27324 0.59174 20.08415 0.53355 3.12173 0.22362 2.81613 0.20174 55535.524295 0.000414 0.13851 0.01065 0.99301 0 22.38949 0.59868 20.11308 0.53775 3.10128 0.22365 2.78364 0.20072 55535.525155 0.000446 0.13110 0.01006 0.99351 0 22.24145 0.57887 19.82875 0.51608 2.91577 0.21045 2.59796 0.18757 55535.526037 0.000437 0.13492 0.01030 1.00000 0 21.71772 0.57273 19.51843 0.51471 2.93015 0.20986 2.62963 0.18838 55535.526882 0.000408 0.14364 0.01084 0.98582 0 22.45267 0.60319 20.18430 0.54227 3.22499 0.22748 2.89691 0.20433 55535.527669 0.000379 0.15221 0.01165 1.00000 0 22.28408 0.62620 20.00193 0.56206 3.39189 0.24145 3.04481 0.21671 55535.528468 0.000420 0.13936 0.01095 0.98621 0 21.69201 0.58374 19.58332 0.52698 3.02296 0.22315 2.72793 0.20138 55535.529267 0.000379 0.16453 0.01280 1.00000 0 20.20925 0.59180 18.36208 0.53761 3.32508 0.23975 3.01738 0.21757 55535.530077 0.000431 0.12888 0.00993 0.99329 0 22.95547 0.59225 20.63357 0.53231 2.95839 0.21474 2.65865 0.19296 55535.530899 0.000391 0.14734 0.01149 0.99259 0 22.11072 0.61269 19.94307 0.55261 3.25786 0.23739 2.93797 0.21407 55535.531680 0.000391 0.15373 0.01190 0.97778 0 21.44712 0.60314 19.47083 0.54758 3.29696 0.23778 2.99453 0.21592 55535.532496 0.000425 0.14000 0.01088 0.98639 0 21.52863 0.57906 19.35764 0.52063 3.01410 0.21965 2.71508 0.19783 55535.533335 0.000414 0.13851 0.01079 1.00000 0 21.79332 0.58774 19.77449 0.53329 3.01859 0.22051 2.73905 0.20010 55535.534220 0.000472 0.12592 0.00955 1.00000 0 21.82125 0.55677 19.42948 0.49572 2.74775 0.19636 2.44833 0.17494 55535.535065 0.000373 0.16092 0.01251 0.99225 0 21.30495 0.61838 19.19566 0.55717 3.42847 0.24716 3.08810 0.22267 55535.535817 0.000379 0.16316 0.01279 0.96947 0 20.87263 0.60277 18.98644 0.54833 3.40556 0.24810 3.09990 0.22587 55535.536581 0.000385 0.15140 0.01179 1.00000 0 21.45551 0.60484 19.52880 0.55050 3.24826 0.23578 2.95850 0.21472 55535.537583 0.000616 0.14665 0.00959 0.98120 0 20.39447 0.47021 18.42239 0.42473 2.99077 0.18292 2.70243 0.16526
