/* ** ** 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 55715.902336 0.000315 0.13511 0.02068 0.96330 0 8.89884 0.45707 7.13604 0.36620 1.20231 0.17338 0.96229 0.13866 55715.903147 0.000495 0.15469 0.01876 0.96491 0 7.81864 0.34184 6.31240 0.27595 1.20947 0.13682 0.97661 0.11049 55715.904026 0.000385 0.10812 0.01653 0.98496 0 8.55883 0.40766 6.93661 0.33032 0.92534 0.13442 0.74869 0.10872 55715.904822 0.000411 0.10881 0.01661 0.97183 0 8.07410 0.37981 6.53269 0.30727 0.87858 0.12759 0.71071 0.10321 55715.905661 0.000428 0.10020 0.01491 0.98649 0 8.64420 0.38752 6.91329 0.30993 0.86618 0.12287 0.69264 0.09825 55715.906457 0.000362 0.11887 0.01802 0.99200 0 8.39172 0.41559 6.72517 0.33306 0.99752 0.14294 0.79938 0.11455 55715.907221 0.000402 0.12643 0.01947 0.97122 0 7.14922 0.36528 5.75007 0.29375 0.90385 0.13128 0.72651 0.10550 55715.907964 0.000341 0.14135 0.02166 0.97458 0 7.58560 0.41111 6.09267 0.33019 1.07221 0.15366 0.86194 0.12351 55715.908665 0.000359 0.12720 0.01983 0.97581 0 7.77447 0.39975 6.32707 0.32530 0.98890 0.14555 0.80194 0.11802 55715.909394 0.000370 0.11908 0.01804 0.96875 0 8.27604 0.40698 6.71382 0.33008 0.98549 0.14118 0.79938 0.11455 55715.910100 0.000330 0.13853 0.02115 0.98246 0 7.88200 0.41664 6.38522 0.33752 1.09186 0.15643 0.88502 0.12682 55715.910864 0.000434 0.11299 0.01727 0.96667 0 7.25075 0.34635 5.98727 0.28599 0.81927 0.11896 0.67640 0.09822 55715.911726 0.000428 0.10596 0.01597 0.97973 0 7.92161 0.36876 6.46359 0.30085 0.83940 0.12030 0.68360 0.09796 55715.912663 0.000509 0.13851 0.01793 0.96023 0 7.60602 0.33280 6.14848 0.26900 1.05354 0.12836 0.85198 0.10377
