/* ** ** 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 55212.703302 0.000310 0.21708 0.01772 0.99065 0 34.64379 1.18556 17.19825 0.57647 7.52063 0.55735 3.71303 0.27068 55212.703841 0.000229 0.24990 0.02033 0.98734 0 37.87635 1.36994 20.10137 0.72407 9.46522 0.68973 5.04354 0.36620 55212.704385 0.000315 0.24277 0.02022 1.00000 0 36.18195 1.31302 14.68667 0.53268 8.78375 0.65835 3.56421 0.26712 55212.705024 0.000324 0.25725 0.02129 1.00000 0 33.41329 1.24943 13.53505 0.50608 8.59554 0.63479 3.48166 0.25720 55212.705666 0.000318 0.26202 0.02179 0.99091 0 33.20893 1.25663 13.58804 0.51415 8.70153 0.64436 3.55910 0.26364 55212.706306 0.000321 0.26492 0.02257 0.99099 0 32.13461 1.22844 13.15153 0.50271 8.51306 0.64804 3.48055 0.26510 55212.706963 0.000336 0.25868 0.02067 0.98276 0 33.51730 1.22251 13.67237 0.49868 8.67025 0.61649 3.53545 0.25139 55212.707591 0.000292 0.28355 0.02424 0.99010 0 33.40186 1.31492 13.49395 0.53117 9.47117 0.71867 3.82675 0.29035 55212.708201 0.000318 0.25717 0.02102 0.98182 0 35.43067 1.31102 14.17618 0.52456 9.11165 0.66419 3.64427 0.26566 55212.708820 0.000301 0.26298 0.02144 0.99038 0 36.26556 1.35872 14.58992 0.54665 9.53719 0.69075 3.83883 0.27800 55212.709445 0.000324 0.25941 0.02194 0.99107 0 33.03418 1.24917 13.36126 0.50521 8.56939 0.64815 3.46557 0.26220 55212.710125 0.000356 0.24190 0.02019 0.99187 0 32.29738 1.17840 13.01044 0.47467 7.81261 0.58665 3.15006 0.23649 55212.710759 0.000278 0.31934 0.02649 0.98958 0 32.63829 1.33768 13.01544 0.53336 10.42279 0.75166 4.16014 0.30006 55212.711346 0.000310 0.28417 0.02367 0.98131 0 32.50648 1.27014 13.06019 0.51032 9.23734 0.67966 3.71200 0.27314 55212.712020 0.000365 0.22500 0.01814 0.99206 0 34.73169 1.19655 13.98596 0.48182 7.81472 0.56973 3.14865 0.22953 55212.712703 0.000318 0.26654 0.02195 0.99091 0 33.23237 1.26175 13.47606 0.51158 8.85789 0.64743 3.59246 0.26258 55212.713441 0.000420 0.23926 0.01750 0.97931 0 35.04824 1.11507 14.18695 0.45137 8.38557 0.55224 3.39376 0.22349
