/* ** ** 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 56108.948213 0.001076 0.45120 0.03911 0.98656 0 2.88568 0.14070 2.38737 0.11638 1.30202 0.09331 1.07892 0.07732 56108.950421 0.001131 0.41046 0.03489 0.97698 0 3.07665 0.14166 2.52984 0.11647 1.26283 0.09024 1.03929 0.07425 56108.951851 0.000298 0.42588 0.07309 0.98058 0 2.78691 0.26410 2.30513 0.21846 1.18688 0.16984 0.98141 0.14045 56108.952455 0.000307 0.42267 0.07180 0.96226 0 2.83359 0.26304 2.31162 0.21456 1.19766 0.17040 0.97691 0.13897 56108.953069 0.000307 0.34032 0.05564 0.96226 0 3.54508 0.29077 2.88860 0.23692 1.20647 0.17063 0.98203 0.13888 56108.954515 0.001140 0.40302 0.03413 0.98223 0 3.07053 0.13962 2.54581 0.11575 1.23749 0.08842 1.02587 0.07330 56108.956003 0.000347 0.37728 0.06214 0.99167 0 2.73538 0.23727 2.27563 0.19739 1.03200 0.14451 0.85857 0.12022 56108.956746 0.000396 0.38528 0.05662 0.98540 0 3.08322 0.23867 2.52921 0.19577 1.18790 0.14840 0.97490 0.12177 56108.957444 0.000301 0.34476 0.05793 0.97115 0 3.38308 0.28824 2.81775 0.24008 1.16635 0.16892 0.97106 0.14064 56108.958815 0.001071 0.44158 0.03792 0.97838 0 3.02411 0.14400 2.48589 0.11836 1.33540 0.09542 1.09671 0.07836 56108.960719 0.000822 0.42995 0.04412 0.97183 0 2.80001 0.15721 2.32105 0.13032 1.20385 0.10342 0.99757 0.08570
