/* ** ** 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 57381.519948 0.000388 0.13695 0.01034 0.99254 0 23.90179 0.62450 22.24901 0.58132 3.27337 0.23194 3.04708 0.21590 57381.520651 0.000315 0.15863 0.01236 0.99083 0 25.01722 0.71443 23.15068 0.66110 3.96852 0.28774 3.66785 0.26600 57381.521288 0.000321 0.16012 0.01236 1.00000 0 24.66057 0.70708 22.46676 0.64416 3.94872 0.28292 3.59951 0.25789 57381.521896 0.000286 0.17646 0.01362 0.97980 0 25.63750 0.76298 23.46277 0.69825 4.52400 0.32218 4.13665 0.29459 57381.522521 0.000339 0.14557 0.01129 1.00000 0 25.49916 0.70426 23.11853 0.63855 3.71180 0.26898 3.36607 0.24391 57381.523203 0.000344 0.14136 0.01100 0.99160 0 25.58930 0.69385 23.51965 0.63765 3.61719 0.26383 3.32306 0.24227 57381.523840 0.000292 0.16532 0.01292 1.00000 0 25.72283 0.75408 23.56272 0.69074 4.25250 0.30816 3.89931 0.28254 57381.524477 0.000344 0.14462 0.01119 0.99160 0 25.27534 0.68759 23.10424 0.62848 3.65544 0.26490 3.33754 0.24184 57381.525160 0.000339 0.14210 0.01097 1.00000 0 25.95657 0.70660 23.80685 0.64807 3.68848 0.26659 3.38319 0.24451 57381.525819 0.000321 0.16325 0.01251 0.99099 0 24.57956 0.70686 22.42015 0.64472 4.01265 0.28508 3.66599 0.26041 57381.526459 0.000318 0.15675 0.01204 0.99091 0 25.70574 0.72821 23.38748 0.66251 4.02931 0.28770 3.66286 0.26151 57381.527107 0.000330 0.15591 0.01200 0.99123 0 24.75423 0.69885 22.52366 0.63583 3.85935 0.27628 3.51547 0.25163 57381.527735 0.000298 0.16159 0.01257 1.00000 0 26.27382 0.75800 23.78236 0.68612 4.24564 0.30684 3.84304 0.27774 57381.528371 0.000339 0.14184 0.01083 1.00000 0 26.57947 0.71777 24.05825 0.64969 3.77002 0.26916 3.41241 0.24363 57381.529002 0.000292 0.17169 0.01341 0.98020 0 25.57086 0.75866 23.28868 0.69090 4.39018 0.31726 3.99832 0.28896 57381.529624 0.000330 0.15826 0.01216 0.99123 0 24.42443 0.69346 22.35418 0.63464 3.86534 0.27597 3.53320 0.25226 57381.530252 0.000298 0.16987 0.01342 0.99029 0 24.88386 0.74120 22.65528 0.67478 4.22697 0.30923 3.84720 0.28146 57381.530883 0.000333 0.14870 0.01148 0.99130 0 25.53863 0.70519 23.46366 0.64781 3.79766 0.27379 3.48980 0.25155 57381.531577 0.000362 0.15765 0.01160 0.99200 0 24.62569 0.66598 22.49469 0.60830 3.88219 0.26579 3.54763 0.24283
