/* ** ** 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 54483.210725 0.000301 0.15781 0.01219 1.00000 0 30.67239 0.87344 24.28586 0.69123 4.84028 0.34745 3.83967 0.27538 54483.211255 0.000229 0.18320 0.01420 0.98734 0 33.68525 1.03655 27.92065 0.85918 6.17130 0.43920 5.11390 0.36394 54483.211753 0.000269 0.15862 0.01224 1.00000 0 32.62269 0.93830 26.93337 0.77462 5.17477 0.37067 4.26991 0.30584 54483.212317 0.000295 0.14298 0.01153 0.99020 0 32.24583 0.89572 26.51451 0.73652 4.61062 0.34920 3.79268 0.28724 54483.212884 0.000272 0.16762 0.01270 0.98936 0 31.87967 0.92419 26.23448 0.76052 5.34364 0.37414 4.39441 0.30767 54483.213451 0.000295 0.14905 0.01161 1.00000 0 31.61575 0.88936 26.02956 0.73222 4.71246 0.34235 3.88000 0.28187 54483.214010 0.000263 0.16200 0.01267 0.98901 0 32.72183 0.95399 26.98767 0.78680 5.30089 0.38464 4.37263 0.31728 54483.214510 0.000237 0.18792 0.01465 1.00000 0 31.44990 0.98041 25.90019 0.80740 5.91010 0.42225 4.86713 0.34773 54483.214967 0.000220 0.19179 0.01511 1.00000 0 32.88969 1.04317 27.12333 0.86029 6.30803 0.45476 5.20157 0.37499 54483.215448 0.000260 0.16473 0.01267 1.00000 0 32.54595 0.94866 26.90347 0.78419 5.36145 0.38156 4.43205 0.31542 54483.215954 0.000246 0.17745 0.01381 1.00000 0 31.83456 0.96982 26.32388 0.80194 5.64898 0.40463 4.67178 0.33463 54483.216478 0.000278 0.16312 0.01258 0.98958 0 31.18408 0.90455 25.75241 0.74700 5.08684 0.36343 4.20110 0.30015 54483.216984 0.000229 0.18021 0.01442 1.00000 0 33.15237 1.02430 27.41286 0.84698 5.97434 0.44085 4.93913 0.36444 54483.217485 0.000272 0.15220 0.01178 0.98936 0 33.69967 0.94808 27.92181 0.78554 5.12915 0.36975 4.25074 0.30644 54483.218034 0.000278 0.14935 0.01150 0.97917 0 34.38319 0.94664 28.31117 0.77942 5.13512 0.36923 4.22683 0.30393 54483.218538 0.000226 0.18123 0.01414 1.00000 0 33.91497 1.04788 28.10400 0.86831 6.14628 0.44024 5.09105 0.36466 54483.219024 0.000260 0.16149 0.01245 0.98889 0 33.75806 0.97270 27.92116 0.80451 5.45147 0.38997 4.50931 0.32258 54483.219559 0.000275 0.15178 0.01167 1.00000 0 33.23623 0.92953 27.53267 0.76999 5.04468 0.36135 4.18002 0.29940 54483.220329 0.000495 0.15384 0.00885 0.98830 0 33.04169 0.69367 27.47144 0.57672 5.08319 0.27234 4.22657 0.22646
