/* ** ** 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 57476.237918 0.000460 0.14488 0.01164 0.98742 0 22.04440 0.62407 16.89854 0.47075 3.19372 0.24007 2.48311 0.18263 57476.238781 0.000402 0.16472 0.01293 0.99281 0 22.69042 0.67623 17.27363 0.51460 3.73761 0.27136 2.85112 0.20696 57476.239530 0.000347 0.18382 0.01433 0.99167 0 24.85662 0.76198 18.12597 0.55546 4.56921 0.32748 3.33664 0.23904 57476.240285 0.000408 0.15274 0.01191 1.00000 0 24.85109 0.70687 18.26466 0.51939 3.79569 0.27559 2.79046 0.20255 57476.241107 0.000414 0.14989 0.01142 0.97902 0 25.64387 0.70645 19.07398 0.52527 3.84379 0.27297 2.86334 0.20328 57476.241920 0.000399 0.16312 0.01277 0.98551 0 24.10721 0.70533 17.71705 0.51825 3.93246 0.28554 2.89305 0.21000 57476.242742 0.000422 0.15572 0.01201 0.97945 0 24.40155 0.68645 18.00788 0.50659 3.79987 0.27294 2.80747 0.20168 57476.243590 0.000425 0.15532 0.01211 0.98639 0 23.90748 0.67930 17.45369 0.49591 3.71340 0.26961 2.71348 0.19697 57476.244443 0.000428 0.15953 0.01245 0.97973 0 23.08020 0.66197 17.02151 0.48818 3.68196 0.26728 2.71348 0.19697 57476.245280 0.000408 0.16539 0.01312 0.99291 0 22.94238 0.67990 16.84659 0.49912 3.79441 0.27910 2.78463 0.20481 57476.246107 0.000420 0.15773 0.01228 1.00000 0 23.86480 0.68517 17.36360 0.49851 3.76408 0.27245 2.72729 0.19745 57476.247010 0.000483 0.14219 0.01105 0.96407 0 23.09531 0.62536 17.19364 0.46553 3.28385 0.23933 2.44506 0.17818 57476.247956 0.000463 0.14707 0.01157 0.98125 0 22.78553 0.63497 16.88594 0.47058 3.35118 0.24651 2.48311 0.18263 57476.248862 0.000443 0.16083 0.01246 0.98693 0 22.81063 0.64719 16.81745 0.47707 3.66871 0.26455 2.70250 0.19484
