/* ** ** 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 58504.182266 0.000472 0.15246 0.01195 0.98773 0 19.54271 0.55369 15.95074 0.45185 2.97955 0.21782 2.43206 0.17778 58504.183114 0.000376 0.19390 0.01531 0.99231 0 19.29474 0.61538 15.88977 0.50676 3.74118 0.27021 3.08054 0.22252 58504.183907 0.000417 0.17540 0.01377 0.96528 0 19.38522 0.57921 16.11967 0.48162 3.40014 0.24689 2.83009 0.20550 58504.184757 0.000434 0.17599 0.01390 0.98667 0 18.08821 0.54998 15.08799 0.45868 3.18330 0.23211 2.65922 0.19387 58504.185620 0.000428 0.17410 0.01362 0.99324 0 18.59158 0.56143 15.42583 0.46583 3.23678 0.23350 2.68846 0.19392 58504.186554 0.000506 0.14037 0.01078 0.98286 0 19.74812 0.53186 16.44957 0.44305 2.77197 0.19937 2.30934 0.16614 58504.187503 0.000443 0.17233 0.01355 0.98693 0 18.32132 0.54810 15.19518 0.45453 3.15734 0.22966 2.61966 0.19048 58504.188386 0.000440 0.16473 0.01276 1.00000 0 19.03003 0.55963 15.84097 0.46571 3.13478 0.22473 2.61201 0.18716 58504.189286 0.000460 0.15416 0.01181 1.00000 0 19.43014 0.54884 16.26185 0.45927 2.99535 0.21322 2.50847 0.17855 58504.190168 0.000422 0.16683 0.01333 1.00000 0 18.93535 0.56708 15.91618 0.47664 3.15892 0.23400 2.65698 0.19684 58504.191025 0.000434 0.16565 0.01287 0.99333 0 19.21197 0.56409 16.09393 0.47253 3.18246 0.22894 2.66582 0.19179 58504.191884 0.000425 0.16800 0.01299 0.96599 0 19.84163 0.57630 16.63668 0.48323 3.33348 0.23891 2.79595 0.20034 58504.192744 0.000434 0.16887 0.01316 0.98667 0 18.90205 0.55654 15.81402 0.46551 3.19198 0.23026 2.67030 0.19261 58504.193626 0.000448 0.15817 0.01247 1.00000 0 18.79827 0.54201 15.97940 0.46073 2.97329 0.21822 2.52738 0.18549 58504.194587 0.000512 0.15530 0.01127 1.00000 0 19.58608 0.52200 16.49546 0.43950 3.04172 0.20532 2.56205 0.17288
