/* ** ** 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 55596.288980 0.000521 0.10668 0.01609 0.93891 0 6.23742 0.29257 5.48962 0.25743 0.66540 0.09536 0.58648 0.08405 55596.289995 0.000495 0.11549 0.01746 0.94152 0 6.06284 0.29213 5.33016 0.25681 0.70018 0.10034 0.61564 0.08823 55596.290996 0.000506 0.10650 0.01586 0.97714 0 6.22198 0.29000 5.50105 0.25639 0.66264 0.09371 0.58577 0.08284 55596.292052 0.000550 0.10289 0.01529 0.97895 0 5.94019 0.27136 5.23872 0.23932 0.61116 0.08643 0.53853 0.07616 55596.293164 0.000561 0.10066 0.01552 0.98454 0 5.74223 0.26320 5.04665 0.23130 0.57802 0.08507 0.50795 0.07477 55596.294046 0.000321 0.06397 0.01484 0.95495 0 6.84030 0.38112 6.04991 0.33708 0.43757 0.09856 0.38699 0.08717 55596.295021 0.000654 0.08159 0.01216 0.97345 0 6.25092 0.25573 5.51885 0.22577 0.50999 0.07309 0.45053 0.06457 55596.296268 0.000593 0.08798 0.01331 0.99512 0 6.22774 0.26552 5.47270 0.23332 0.54791 0.07956 0.48073 0.06982 55596.297171 0.000310 0.08184 0.01860 0.99065 0 5.50923 0.34875 4.83465 0.30603 0.45089 0.09839 0.39689 0.08661 55596.298074 0.000593 0.09336 0.01403 0.97561 0 6.10997 0.26704 5.35789 0.23415 0.57041 0.08200 0.50036 0.07192 55596.299665 0.000998 0.11032 0.01212 0.96812 0 5.91549 0.20158 5.16095 0.17586 0.65259 0.06814 0.56924 0.05941
