/* ** ** 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 58935.410550 0.000527 0.22594 0.00805 1.00000 0 53.52136 0.81779 48.26239 0.73735 12.09269 0.38913 10.90432 0.35091 58935.411800 0.000723 0.22605 0.00687 0.99705 0 53.72959 0.69863 49.02523 0.63746 12.14547 0.33356 11.08156 0.30433 58935.871954 0.000420 0.16534 0.01354 0.99310 0 43.57092 1.32264 15.95340 0.48391 7.20383 0.54791 2.64482 0.20107 58935.872808 0.000434 0.17702 0.01438 0.98667 0 42.50014 1.32462 14.66648 0.45708 7.52341 0.56447 2.59768 0.19488 58935.873621 0.000379 0.19789 0.01632 0.99237 0 42.81494 1.41541 14.87287 0.49170 8.47270 0.64015 2.94350 0.22229 58935.874379 0.000379 0.19869 0.01629 0.97710 0 44.00842 1.44737 15.20893 0.50019 8.74415 0.65687 3.02079 0.22685 58935.875157 0.000399 0.19225 0.01535 0.99275 0 43.22443 1.38782 14.87038 0.47753 8.31004 0.60728 2.85884 0.20888 58935.875933 0.000376 0.20993 0.01692 0.98462 0 41.90638 1.40243 14.57969 0.48780 8.79757 0.64521 3.06143 0.22455 58935.876729 0.000420 0.19412 0.01574 0.97931 0 40.70176 1.31899 14.10450 0.45692 7.90085 0.58733 2.73423 0.20321 58935.877562 0.000414 0.18516 0.01501 0.96503 0 43.55391 1.36032 15.10718 0.47186 8.06424 0.60320 2.80043 0.20950 58935.878424 0.000448 0.18435 0.01463 0.98710 0 40.15105 1.26276 13.97046 0.43932 7.40204 0.53926 2.57297 0.18749 58935.879289 0.000417 0.20101 0.01608 0.98611 0 39.53626 1.30107 13.79687 0.45389 7.94726 0.57924 2.77228 0.20202 58935.880114 0.000408 0.20176 0.01628 0.99291 0 40.18585 1.33377 13.80199 0.45797 8.10791 0.59647 2.78471 0.20481 58935.881231 0.000709 0.18202 0.01167 0.97143 0 41.07859 1.01324 14.16328 0.34934 7.47698 0.44237 2.57834 0.15256
