/* ** ** Swift/XRT hardness ratio for 3C 273. ** 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 57522.041459 0.000392 0.65583 0.16799 0.96296 1 2.34030 0.37453 0.58596 0.09378 1.53484 0.30697 0.38462 0.07692 57522.042214 0.000363 0.48979 0.13615 0.96000 1 2.72219 0.43596 0.67827 0.10861 1.33332 0.30292 0.32836 0.07462 57522.042911 0.000334 0.57582 0.16306 0.95652 1 2.49554 0.42770 0.62822 0.10767 1.43697 0.32393 0.36092 0.08136 57522.043696 0.000450 0.40153 0.10592 0.93548 1 2.74125 0.38370 0.68737 0.09621 1.10069 0.24612 0.27586 0.06169 57522.044567 0.000421 0.38307 0.10233 0.96552 1 2.91364 0.40908 0.73433 0.10310 1.11614 0.25364 0.28145 0.06396 57522.045381 0.000392 0.43197 0.11726 0.96296 1 2.81164 0.41749 0.70310 0.10439 1.21455 0.27600 0.30310 0.06888 57522.046412 0.000610 0.64273 0.12968 0.97619 1 2.42015 0.30329 0.60811 0.07620 1.55551 0.24596 0.39025 0.06170 57522.047400 0.000378 0.39613 0.10552 0.96154 1 3.20242 0.46357 0.80672 0.11677 1.26858 0.28367 0.32000 0.07155 57522.048141 0.000363 0.40627 0.11057 1.00000 1 3.08606 0.47063 0.78182 0.11923 1.25377 0.28261 0.31761 0.07159 57522.048896 0.000392 0.48973 0.13751 0.96296 1 2.47810 0.41487 0.62350 0.10438 1.21361 0.27357 0.30540 0.06884 57522.049680 0.000392 0.42675 0.11368 0.96296 1 2.94476 0.42767 0.74237 0.10782 1.25668 0.28064 0.31619 0.07061 57522.051060 0.000988 0.45014 0.06752 0.99775 1 3.44781 0.29278 0.86782 0.07369 1.55200 0.19191 0.39061 0.04830
