/* ** ** 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 53909.672366 0.000324 0.42938 0.01673 1.00000 0 51.78595 1.09704 40.89278 0.86626 22.23601 0.72724 17.54078 0.57372 53909.673034 0.000344 0.40821 0.01571 1.00000 0 54.65167 1.13595 40.64820 0.84474 22.30919 0.72250 16.59238 0.53738 53909.673743 0.000365 0.39092 0.01492 1.00000 0 54.57102 1.10153 40.16376 0.81074 21.33277 0.69079 15.70573 0.50859 53909.674460 0.000353 0.40415 0.01560 1.00000 0 54.16082 1.11583 39.79449 0.81986 21.88917 0.71480 16.08061 0.52512 53909.675175 0.000362 0.40239 0.01551 1.00000 0 53.50313 1.10413 39.07857 0.80645 21.52927 0.70061 15.72234 0.51164 53909.675899 0.000362 0.41225 0.01591 1.00000 0 52.32587 1.09209 38.20467 0.79737 21.57157 0.70013 15.75146 0.51123 53909.676622 0.000362 0.38426 0.01458 1.00000 0 56.51133 1.13304 41.25519 0.82715 21.71530 0.69940 15.85633 0.51069 53909.677337 0.000353 0.41051 0.01581 1.00000 0 53.90514 1.12146 39.31292 0.81789 22.12884 0.71708 16.13579 0.52286 53909.678031 0.000341 0.43206 0.01671 1.00000 0 52.97058 1.12266 38.82006 0.82274 22.88642 0.74026 16.76921 0.54240 53909.678734 0.000362 0.40195 0.01548 1.00000 0 53.40076 1.10189 39.11235 0.80707 21.46460 0.69793 15.72087 0.51118 53909.679455 0.000359 0.40641 0.01571 1.00000 0 53.46932 1.10672 38.92684 0.80573 21.73031 0.70956 15.82125 0.51665 53909.680181 0.000367 0.42335 0.01642 1.00000 0 50.38310 1.06790 36.61974 0.77615 21.32973 0.69285 15.50485 0.50363 53909.680945 0.000396 0.37145 0.01420 1.00000 0 52.89702 1.04603 38.56847 0.76268 19.64847 0.64314 14.32397 0.46887 53909.681743 0.000402 0.37736 0.01441 1.00000 0 52.03275 1.04235 37.51209 0.75144 19.63522 0.63858 14.15320 0.46033 53909.682530 0.000385 0.38289 0.01464 1.00000 0 53.41867 1.07386 38.55758 0.77509 20.45369 0.66545 14.76019 0.48020 53909.683300 0.000385 0.38913 0.01488 1.00000 0 52.83410 1.06706 38.20851 0.77166 20.55932 0.66749 14.86838 0.48271 53909.684261 0.000576 0.40714 0.01257 1.00000 0 52.10084 0.86201 37.83733 0.62601 21.21243 0.55264 15.40360 0.40130
