/* ** ** 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 58879.109033 0.000200 0.18260 0.01431 0.98551 0 36.65710 1.12623 31.83832 0.97818 6.69366 0.48252 5.81374 0.41909 58879.109427 0.000194 0.18625 0.01453 1.00000 0 37.23543 1.15233 32.34063 1.00085 6.93516 0.49667 6.02349 0.43138 58879.109829 0.000208 0.16464 0.01321 1.00000 0 37.53387 1.12091 32.59983 0.97356 6.17971 0.46012 5.36735 0.39963 58879.110248 0.000211 0.16241 0.01311 0.98630 0 37.89816 1.10884 32.91623 0.96308 6.15491 0.46298 5.34581 0.40212 58879.110659 0.000200 0.17270 0.01336 0.98551 0 39.12903 1.16370 33.98530 1.01073 6.75767 0.48277 5.86933 0.41931 58879.111047 0.000188 0.18936 0.01477 1.00000 0 37.33353 1.16742 32.42583 1.01396 7.06956 0.50505 6.14022 0.43866 58879.111461 0.000226 0.16251 0.01285 0.98718 0 35.88368 1.04901 31.16657 0.91111 5.83157 0.42860 5.06498 0.37226 58879.111880 0.000194 0.17430 0.01378 0.98507 0 39.43317 1.18432 34.24947 1.02864 6.87339 0.50247 5.96985 0.43642 58879.112280 0.000205 0.17037 0.01354 1.00000 0 37.33399 1.12378 32.42623 0.97605 6.36053 0.46797 5.52441 0.40645 58879.112847 0.000362 0.15174 0.00927 0.99017 0 38.87824 0.85798 33.76748 0.74520 5.89931 0.33592 5.12381 0.29176 58879.156170 0.000211 0.14490 0.01107 1.00000 0 40.20237 1.09801 37.75505 1.03117 5.82535 0.41569 5.47073 0.39038 58879.156560 0.000179 0.17400 0.01354 1.00000 0 39.25671 1.17872 36.86695 1.10697 6.83049 0.49026 6.41468 0.46042 58879.156948 0.000208 0.14359 0.01094 1.00000 0 41.09534 1.12091 38.59366 1.05268 5.90107 0.41971 5.54184 0.39416 58879.157345 0.000188 0.17292 0.01354 1.00000 0 37.74319 1.14010 35.44557 1.07070 6.52672 0.47149 6.12941 0.44279 58879.157727 0.000194 0.15214 0.01179 1.00000 0 41.37408 1.16453 38.85542 1.09364 6.29448 0.45444 5.91131 0.42677 58879.158123 0.000203 0.16442 0.01245 0.99860 0 39.14001 1.12203 36.75735 1.05373 6.43522 0.45099 6.04347 0.42354
