/* ** ** 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 57385.049750 0.000324 0.14686 0.01140 1.00000 0 26.67676 0.73441 23.90155 0.65801 3.91782 0.28430 3.51037 0.25473 57385.050366 0.000292 0.17172 0.01351 1.00000 0 25.32188 0.75748 22.69794 0.67899 4.34821 0.31634 3.89766 0.28356 57385.050957 0.000298 0.15532 0.01205 1.00000 0 27.84310 0.79290 24.65401 0.70201 4.32453 0.31220 3.83167 0.27660 57385.051567 0.000312 0.15034 0.01187 1.00000 0 26.68298 0.75461 23.93732 0.67696 4.01145 0.29568 3.59868 0.26526 57385.052198 0.000318 0.15649 0.01210 0.98182 0 26.77756 0.75408 23.63131 0.66539 4.19040 0.30166 3.69603 0.26611 57385.052823 0.000307 0.15862 0.01258 0.95283 0 27.25364 0.77105 24.15943 0.68348 4.32309 0.32031 3.83323 0.28403 57385.053454 0.000324 0.15004 0.01164 1.00000 0 26.45592 0.73857 23.51229 0.65632 3.96945 0.28726 3.52825 0.25536 57385.054122 0.000344 0.14927 0.01138 0.99160 0 25.78716 0.71159 22.81792 0.62965 3.84930 0.27359 3.40399 0.24196 57385.054747 0.000281 0.16689 0.01295 1.00000 0 27.74138 0.81576 24.48365 0.71996 4.62983 0.33257 4.08416 0.29330 57385.055320 0.000292 0.16839 0.01307 1.00000 0 26.72214 0.78850 23.29392 0.68734 4.49962 0.32314 3.92241 0.28169 57385.055893 0.000281 0.18637 0.01459 1.00000 0 24.81075 0.77332 21.88560 0.68211 4.62407 0.33211 4.08416 0.29330 57385.056480 0.000307 0.15810 0.01241 0.98113 0 27.17602 0.77484 23.84464 0.67978 4.29646 0.31428 3.77079 0.27576 57385.057056 0.000269 0.17443 0.01375 0.98925 0 28.17259 0.84465 24.56280 0.73643 4.91407 0.35841 4.28441 0.31248 57385.057609 0.000284 0.16661 0.01288 0.97959 0 28.21161 0.81916 24.90248 0.72298 4.70029 0.33670 4.14757 0.29709 57385.058191 0.000298 0.16698 0.01290 1.00000 0 26.39483 0.77464 23.28902 0.68339 4.40729 0.31492 3.88515 0.27758 57385.058752 0.000263 0.18258 0.01397 1.00000 0 27.91170 0.85038 24.49660 0.74630 5.09626 0.35770 4.46898 0.31366 57385.059296 0.000281 0.15816 0.01243 1.00000 0 28.86394 0.83252 25.60017 0.73829 4.56498 0.33380 4.04291 0.29565 57385.059993 0.000417 0.17606 0.01136 0.97222 0 25.87305 0.64222 23.10158 0.57340 4.55524 0.27130 4.07108 0.24247
