/* ** ** 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 55952.330314 0.000321 0.50365 0.08787 0.98198 0 2.30583 0.23557 1.82684 0.18661 1.16134 0.16425 0.91896 0.12996 55952.331023 0.000388 0.33650 0.05563 0.97761 0 2.80673 0.23318 2.25065 0.18698 0.94447 0.13500 0.75736 0.10826 55952.331778 0.000367 0.41200 0.06956 0.96063 0 2.49713 0.22712 2.00414 0.18228 1.02880 0.14635 0.82574 0.11746 55952.332525 0.000379 0.36393 0.06013 0.96947 0 2.72976 0.23292 2.18964 0.18683 0.99345 0.14057 0.79699 0.11278 55952.333266 0.000362 0.41888 0.07101 0.98400 0 2.41120 0.22258 1.93511 0.17863 1.01000 0.14360 0.81049 0.11523 55952.333977 0.000350 0.47577 0.08335 0.97521 0 2.17971 0.21595 1.74950 0.17332 1.03704 0.14984 0.83272 0.12032 55952.334704 0.000376 0.38438 0.06458 0.97692 0 2.53359 0.22371 2.03222 0.17944 0.97386 0.13921 0.78121 0.11167 55952.335517 0.000437 0.27056 0.04381 0.97351 0 3.09149 0.23057 2.48165 0.18509 0.83642 0.12020 0.67168 0.09653 55952.336281 0.000327 0.45751 0.07833 0.98230 0 2.46018 0.23738 1.97213 0.19029 1.12557 0.15918 0.90240 0.12762 55952.337021 0.000414 0.34114 0.05633 0.96503 0 2.62277 0.21676 2.10760 0.17418 0.89474 0.12789 0.71894 0.10277 55952.337808 0.000373 0.53371 0.08459 0.96899 0 2.30005 0.21468 1.84713 0.17240 1.22756 0.15725 0.98603 0.12631 55952.338569 0.000388 0.38436 0.06415 0.94030 0 2.56372 0.22414 2.05882 0.18000 0.98539 0.14010 0.79119 0.11249 55952.339319 0.000362 0.41867 0.07063 0.96800 0 2.45976 0.22622 1.97702 0.18182 1.02984 0.14564 0.82782 0.11707 55952.340007 0.000327 0.47360 0.08132 1.00000 0 2.37889 0.23638 1.90886 0.18968 1.12664 0.15776 0.90416 0.12661 55952.340945 0.000611 0.32067 0.04382 0.96209 0 2.75145 0.18389 2.21004 0.14770 0.88229 0.10518 0.70868 0.08448
