/* ** ** 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 56779.927901 0.000234 0.19792 0.01542 0.98765 0 28.74639 0.90961 25.17454 0.79657 5.68962 0.40505 4.98527 0.35489 56779.928381 0.000246 0.17733 0.01383 1.00000 0 29.84249 0.91005 26.46277 0.80699 5.29195 0.37983 4.69577 0.33707 56779.928899 0.000272 0.15608 0.01207 0.98936 0 30.61995 0.86751 27.35972 0.77514 4.77914 0.34395 4.27029 0.30732 56779.929391 0.000220 0.19465 0.01522 1.00000 0 30.20257 0.95794 26.97057 0.85543 5.87904 0.42027 5.24975 0.37528 56779.929839 0.000229 0.19938 0.01545 1.00000 0 28.77042 0.91668 25.70209 0.81892 5.73624 0.40528 5.12445 0.36206 56779.930305 0.000237 0.18803 0.01462 1.00000 0 28.97019 0.90409 25.86705 0.80725 5.44723 0.38778 4.86368 0.34624 56779.930791 0.000249 0.17127 0.01346 1.00000 0 29.89962 0.89658 26.70211 0.80070 5.12079 0.37200 4.57313 0.33221 56779.931289 0.000249 0.17806 0.01377 0.98837 0 29.52563 0.89205 26.35046 0.79612 5.25725 0.37425 4.69202 0.33402 56779.931792 0.000255 0.17402 0.01357 0.98864 0 29.37497 0.88039 26.23192 0.78619 5.11174 0.36788 4.56479 0.32852 56779.932345 0.000298 0.18262 0.01279 0.98065 0 29.54976 0.81692 26.40097 0.72987 5.39626 0.34737 4.82114 0.31035
