/* ** ** 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 58549.347872 0.000365 0.40628 0.06839 0.97619 0 2.46165 0.22443 2.02541 0.18466 1.00013 0.14152 0.82289 0.11644 58549.348665 0.000428 0.44233 0.07547 0.95946 0 1.92972 0.18201 1.58706 0.14969 0.85358 0.12136 0.70204 0.09982 58549.349466 0.000373 0.40559 0.06825 0.96899 0 2.41534 0.22021 1.97640 0.18019 0.97963 0.13855 0.80133 0.11333 58549.350158 0.000318 0.49379 0.08731 0.98182 0 2.26194 0.23300 1.84797 0.19033 1.11693 0.16051 0.91422 0.13139 58549.350898 0.000422 0.38212 0.06449 0.97945 0 2.21622 0.19884 1.81526 0.16285 0.84687 0.12105 0.69379 0.09917 58549.351795 0.000475 0.39240 0.06742 0.98171 0 1.87744 0.16976 1.53754 0.13903 0.73671 0.10763 0.60438 0.08828 58549.352733 0.000463 0.39965 0.06866 0.98750 0 1.89588 0.17622 1.55316 0.14437 0.75769 0.10948 0.62189 0.08986 58549.353685 0.000489 0.32102 0.05261 0.93491 0 2.41277 0.19333 1.95504 0.15664 0.77455 0.11074 0.62793 0.08976 58549.354651 0.000477 0.36062 0.06058 0.96364 0 2.12101 0.18442 1.72079 0.14963 0.76487 0.10994 0.62098 0.08924 58549.355667 0.000538 0.30931 0.05039 0.97312 0 2.19812 0.17479 1.78214 0.14171 0.67990 0.09668 0.55077 0.07831 58549.356581 0.000376 0.47603 0.08287 0.94615 0 2.10419 0.20907 1.69154 0.16809 1.00165 0.14319 0.80661 0.11530 58549.357281 0.000324 0.20512 0.04825 0.99107 0 2.38660 0.23715 1.94303 0.19300 0.48953 0.10438 0.39706 0.08465 58549.358196 0.000590 0.31099 0.04980 0.97059 0 2.09557 0.16750 1.71061 0.13672 0.65171 0.09043 0.53143 0.07374
