/* ** ** 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 60075.986977 0.000414 0.25904 0.00930 1.00000 0 57.95591 0.94592 53.67182 0.87600 15.01309 0.48036 13.90328 0.44482 60075.987822 0.000431 0.23123 0.00834 1.00000 0 61.60714 0.95931 57.07577 0.88877 14.24515 0.46344 13.19800 0.42938 60075.988704 0.000451 0.22672 0.00804 1.00000 0 61.02481 0.93340 56.26330 0.86044 13.83533 0.44290 12.75646 0.40840 60075.989592 0.000437 0.23919 0.00852 1.00000 0 59.58794 0.93568 55.14927 0.86591 14.25311 0.45556 13.19321 0.42168 60075.990489 0.000460 0.21883 0.00772 1.00000 0 61.87380 0.92770 57.27856 0.85876 13.54012 0.43229 12.53043 0.40003 60075.991395 0.000446 0.22927 0.00816 1.00000 0 60.67783 0.93514 56.17279 0.86568 13.91161 0.44658 12.88205 0.41353 60075.992266 0.000425 0.24121 0.00857 1.00000 0 61.38026 0.96930 56.31971 0.88939 14.80543 0.47110 13.58280 0.43218 60075.993108 0.000417 0.25284 0.00903 1.00000 0 59.50002 0.95848 54.82972 0.88321 15.04370 0.47922 13.86464 0.44166 60075.993970 0.000446 0.22892 0.00813 0.99351 0 61.60313 0.94378 56.77724 0.86980 14.10231 0.45171 12.99350 0.41620 60075.994879 0.000463 0.23124 0.00819 1.00000 0 59.28560 0.91602 53.86099 0.83220 13.70910 0.43714 12.45314 0.39710 60075.995773 0.000431 0.23985 0.00855 1.00000 0 60.60121 0.95172 55.72408 0.87512 14.53527 0.46518 13.36921 0.42779 60075.996658 0.000454 0.22856 0.00811 1.00000 0 60.70467 0.92941 55.67567 0.85234 13.87477 0.44388 12.72521 0.40703 60075.997550 0.000437 0.23039 0.00822 1.00000 0 61.53287 0.94974 56.95554 0.87905 14.17656 0.45584 13.12363 0.42199 60075.998415 0.000428 0.24182 0.00870 0.99324 0 60.16995 0.94994 55.67513 0.87895 14.55051 0.47027 13.46266 0.43511 60075.999416 0.000573 0.23533 0.00734 1.00000 0 59.97718 0.81999 55.39590 0.75735 14.11445 0.39598 13.03532 0.36570
