/* ** ** 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 57929.813233 0.000492 0.15559 0.01201 0.98235 0 16.96256 0.47599 15.22707 0.42729 2.63913 0.18974 2.36899 0.17032 57929.814295 0.000570 0.13525 0.01040 0.97462 0 17.01850 0.44601 15.22145 0.39890 2.30181 0.16643 2.05782 0.14880 57929.815412 0.000547 0.14634 0.01119 1.00000 0 16.18085 0.44237 14.44207 0.39481 2.36787 0.16912 2.11051 0.15072 57929.816462 0.000503 0.15618 0.01188 0.98851 0 16.90404 0.47183 15.05309 0.42014 2.64008 0.18682 2.34973 0.16627 57929.817446 0.000480 0.16867 0.01314 0.97590 0 16.32935 0.47773 14.44557 0.42257 2.75424 0.19882 2.43432 0.17575 57929.818386 0.000460 0.17933 0.01404 0.98742 0 16.07457 0.48767 14.00642 0.42493 2.88271 0.20812 2.51184 0.18135 57929.819408 0.000561 0.13410 0.01043 0.99485 0 17.14103 0.45318 15.08362 0.39875 2.29853 0.16806 2.02370 0.14795 57929.820464 0.000495 0.14728 0.01130 1.00000 0 18.00243 0.49721 15.74689 0.43489 2.65141 0.18984 2.32095 0.16617 57929.821471 0.000512 0.14187 0.01102 0.98305 0 17.94336 0.48369 15.87489 0.42789 2.54558 0.18535 2.25193 0.16395 57929.822420 0.000437 0.18321 0.01410 0.96026 0 17.07398 0.51438 15.11437 0.45530 3.12813 0.22156 2.76834 0.19607 57929.823389 0.000532 0.15764 0.01200 0.98370 0 16.09430 0.45091 14.17010 0.39697 2.53708 0.17953 2.23289 0.15800 57929.824460 0.000538 0.15092 0.01128 0.97312 0 17.54927 0.46980 15.39457 0.41211 2.64857 0.18479 2.31857 0.16176
