/* ** ** 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 55228.292247 0.000723 0.14011 0.01355 0.98000 0 8.15188 0.27655 7.12129 0.24158 1.14215 0.10341 0.99758 0.09032 55228.293271 0.000301 0.15231 0.02347 1.00000 0 7.16173 0.40608 6.26182 0.35499 1.09080 0.15628 0.95317 0.13657 55228.293899 0.000327 0.13120 0.02004 0.98230 0 7.81452 0.40456 6.87309 0.35582 1.02527 0.14731 0.90176 0.12956 55228.294570 0.000344 0.11814 0.01790 0.99160 0 8.13521 0.40143 7.11869 0.35121 0.96111 0.13770 0.84008 0.12037 55228.295230 0.000315 0.14162 0.02162 0.94495 0 7.72852 0.40767 6.79537 0.35845 1.09452 0.15683 0.96242 0.13790 55228.295898 0.000347 0.12055 0.01806 0.99167 0 7.93737 0.39282 6.98275 0.34557 0.95689 0.13532 0.84174 0.11904 55228.296659 0.000414 0.09800 0.01489 0.97203 0 8.20128 0.36708 7.18474 0.32155 0.80374 0.11669 0.70570 0.10246 55228.297423 0.000350 0.13079 0.01968 0.97521 0 7.37760 0.37868 6.49056 0.33314 0.96495 0.13646 0.84887 0.12005 55228.298248 0.000469 0.08694 0.01283 0.98765 0 8.23433 0.34628 7.19680 0.30264 0.71592 0.10125 0.62604 0.08854 55228.299275 0.000558 0.13639 0.01535 0.95855 0 8.22042 0.31606 7.21159 0.27726 1.12120 0.11857 0.98504 0.10417 55228.300421 0.000587 0.14195 0.01565 0.95074 0 7.88910 0.30097 6.94419 0.26492 1.11990 0.11587 0.98573 0.10199 55228.301312 0.000304 0.13999 0.02194 0.96190 0 7.84201 0.42235 6.86203 0.36954 1.09782 0.16154 0.96093 0.14138 55228.302524 0.000909 0.15409 0.01293 0.97134 0 8.19506 0.24726 7.17477 0.21646 1.26280 0.09890 1.10594 0.08661
