/* ** ** 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 59196.261655 0.000558 0.21425 0.01729 0.95855 0 22.12330 0.73417 9.77215 0.32303 4.73982 0.34864 2.11035 0.15487 59196.262729 0.000515 0.19905 0.01616 0.97753 0 21.20600 0.69181 11.22250 0.36608 4.22112 0.31392 2.22963 0.16595 59196.263742 0.000498 0.20960 0.01686 0.98837 0 21.12494 0.70560 11.00132 0.36732 4.42781 0.32406 2.30277 0.16840 59196.264737 0.000498 0.21580 0.01706 0.97674 0 20.68137 0.69055 10.92719 0.36482 4.46305 0.31981 2.36303 0.16935 59196.265698 0.000463 0.22001 0.01766 0.99375 0 21.35032 0.72937 11.26153 0.38476 4.69720 0.34115 2.47365 0.17968 59196.266554 0.000394 0.25637 0.02073 0.98529 0 21.97316 0.80344 11.50522 0.42064 5.63332 0.40625 2.94887 0.21276 59196.267327 0.000379 0.25774 0.02124 1.00000 0 21.72035 0.81262 11.60213 0.43406 5.59824 0.41109 2.98958 0.21952 59196.268088 0.000382 0.23590 0.01905 0.99242 0 23.52226 0.82988 12.72946 0.44907 5.54879 0.40302 3.00236 0.21809 59196.268883 0.000414 0.21899 0.01738 0.97902 0 23.86748 0.81119 12.94462 0.43987 5.22676 0.37476 2.83563 0.20322 59196.270052 0.000755 0.20698 0.01221 0.99234 0 24.25219 0.59102 13.37129 0.32567 5.01979 0.26955 2.76515 0.14839
