/* ** ** 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 58142.503914 0.000503 0.38931 0.06570 0.97701 0 1.74350 0.15581 1.49800 0.13387 0.67876 0.09716 0.58293 0.08345 58142.504921 0.000503 0.40866 0.06900 0.96552 0 1.70905 0.15462 1.46911 0.13290 0.69842 0.09957 0.59861 0.08534 58142.505957 0.000532 0.37646 0.06268 0.96196 0 1.75791 0.15372 1.51539 0.13250 0.66178 0.09378 0.57119 0.08094 58142.506932 0.000443 0.44809 0.07724 0.96732 0 1.72797 0.16597 1.49437 0.14352 0.77428 0.11084 0.66958 0.09585 58142.507742 0.000367 0.54128 0.09573 0.96850 0 1.75451 0.18355 1.50633 0.15756 0.94967 0.13542 0.81762 0.11656 58142.508590 0.000480 0.41566 0.07031 0.98795 0 1.71723 0.15932 1.46993 0.13635 0.71378 0.10095 0.61077 0.08638 58142.509562 0.000492 0.45375 0.07801 0.96471 0 1.56474 0.15099 1.33636 0.12895 0.71000 0.10102 0.60751 0.08644 58142.510610 0.000556 0.36906 0.06195 0.95312 0 1.72258 0.15094 1.47275 0.12903 0.63574 0.09102 0.54152 0.07752 58142.511463 0.000298 0.64384 0.11762 0.98058 0 1.78148 0.20599 1.54270 0.17838 1.14699 0.16222 0.99175 0.14025 58142.512395 0.000634 0.24927 0.03950 0.95434 0 2.25291 0.16102 1.92683 0.13770 0.56159 0.07943 0.47927 0.06778 58142.513796 0.000767 0.33821 0.04672 0.94717 0 1.96620 0.13679 1.67951 0.11684 0.66499 0.07937 0.56827 0.06782
