/* ** ** 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 60050.603140 0.000450 0.53710 0.14761 0.93548 1 1.04587 0.16705 0.51124 0.08166 0.56174 0.12563 0.27586 0.06169 60050.603939 0.000349 0.71045 0.21452 1.00000 1 0.97589 0.19450 0.46583 0.09280 0.69332 0.15726 0.32912 0.07460 60050.604666 0.000378 0.69202 0.20153 0.96154 1 0.93344 0.17414 0.46198 0.08619 0.64596 0.14444 0.32000 0.07155 60050.605392 0.000349 0.61727 0.17809 1.00000 1 1.08887 0.19645 0.53693 0.09686 0.67213 0.15133 0.33123 0.07457 60050.606234 0.000494 0.38412 0.10158 0.97059 1 1.28746 0.18174 0.63276 0.08931 0.49455 0.11059 0.24243 0.05421 60050.607338 0.000610 0.47642 0.13136 1.00000 1 0.81911 0.13042 0.39747 0.06327 0.39024 0.08784 0.18927 0.04261 60050.608370 0.000421 0.55556 0.15147 0.96552 1 1.10109 0.17991 0.53925 0.08810 0.61172 0.13351 0.30000 0.06547 60050.609299 0.000508 0.44085 0.11674 1.00000 1 1.11383 0.16473 0.53969 0.07981 0.49103 0.10786 0.23856 0.05239 60050.610374 0.000566 0.53375 0.14647 1.00000 1 0.82553 0.13574 0.40000 0.06576 0.44063 0.09680 0.21409 0.04702 60050.611289 0.000349 0.64926 0.18654 0.95833 1 1.11043 0.20033 0.53693 0.09686 0.72096 0.16122 0.34783 0.07778 60050.612408 0.000770 0.61485 0.13464 0.90756 1 0.91540 0.12156 0.44607 0.05922 0.56283 0.09799 0.27443 0.04777
