/* ** ** 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 59317.005404 0.000304 0.16967 0.01320 1.00000 0 25.07433 0.74441 22.20256 0.65915 4.25441 0.30589 3.76770 0.27090 59317.006000 0.000292 0.17280 0.01353 1.00000 0 25.20519 0.75627 22.63780 0.67923 4.35542 0.31496 3.91171 0.28288 59317.006590 0.000298 0.16983 0.01337 1.00000 0 25.01938 0.74720 22.38308 0.66840 4.24900 0.30943 3.80403 0.27697 59317.007218 0.000330 0.16038 0.01239 0.98246 0 24.79253 0.70627 22.17207 0.63159 3.97633 0.28560 3.55670 0.25547 59317.007860 0.000312 0.16469 0.01277 0.99074 0 25.12248 0.73045 22.47232 0.65336 4.13744 0.29746 3.69728 0.26583 59317.008494 0.000321 0.17140 0.01325 0.97297 0 24.10807 0.70731 21.56521 0.63266 4.13202 0.29559 3.70014 0.26467 59317.009275 0.000460 0.14809 0.00988 0.99754 0 24.92666 0.59716 22.41850 0.53707 3.69134 0.22990 3.31988 0.20677 59317.079005 0.000373 0.15102 0.01176 0.99225 0 27.58359 0.77226 20.55776 0.57401 4.16576 0.30275 3.10415 0.22428 59317.079705 0.000327 0.16643 0.01345 1.00000 0 25.77440 0.77872 20.56274 0.62066 4.28958 0.32143 3.41727 0.25603 59317.080388 0.000356 0.15723 0.01218 0.97561 0 24.90083 0.70358 20.93792 0.59158 3.91509 0.28252 3.29300 0.23758 59317.081088 0.000344 0.15878 0.01216 1.00000 0 25.03058 0.71966 21.20353 0.60960 3.97435 0.28219 3.36835 0.23917 59317.081791 0.000359 0.15841 0.01241 1.00000 0 23.86013 0.70086 20.04317 0.58862 3.77980 0.27446 3.17197 0.23039 59317.082732 0.000582 0.15349 0.00950 0.99502 0 24.87607 0.55254 20.95627 0.46547 3.81812 0.22057 3.21625 0.18576
