/* ** ** 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 58603.210839 0.000515 0.35214 0.05923 0.96067 0 1.90946 0.16349 1.62776 0.13937 0.67239 0.09734 0.57371 0.08306 58603.211759 0.000405 0.52559 0.09225 0.98571 0 1.61263 0.16762 1.38122 0.14357 0.84758 0.11987 0.72585 0.10265 58603.212688 0.000524 0.34758 0.05824 0.97238 0 1.87389 0.15807 1.60330 0.13524 0.65132 0.09430 0.55742 0.08070 58603.213637 0.000425 0.38555 0.06462 0.98639 0 2.11255 0.18930 1.80953 0.16214 0.81450 0.11536 0.69751 0.09879 58603.214496 0.000434 0.35966 0.06115 0.98667 0 2.13797 0.18763 1.83318 0.16088 0.76893 0.11198 0.65939 0.09603 58603.215497 0.000567 0.39034 0.06585 0.98469 0 1.54221 0.13988 1.32259 0.11997 0.60199 0.08563 0.51633 0.07345 58603.216614 0.000550 0.36498 0.05978 0.96842 0 1.77653 0.15093 1.52098 0.12922 0.64839 0.09079 0.55527 0.07775 58603.217934 0.000770 0.40090 0.05472 0.97966 0 1.72410 0.12691 1.47633 0.10868 0.69119 0.07944 0.59173 0.06801
