/* ** ** 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 59315.481510 0.000616 0.38128 0.06452 0.98122 0 1.52351 0.13673 1.24068 0.11133 0.58089 0.08334 0.47313 0.06787 59315.482714 0.000587 0.40979 0.06886 0.95567 0 1.54572 0.14029 1.26544 0.11485 0.63342 0.08959 0.51632 0.07302 59315.483860 0.000558 0.37917 0.06349 0.96373 0 1.73879 0.15213 1.41340 0.12365 0.65929 0.09413 0.53393 0.07623 59315.484893 0.000475 0.47094 0.08130 0.96341 0 1.63511 0.16030 1.34292 0.13165 0.77003 0.10942 0.63126 0.08970 59315.485847 0.000480 0.48122 0.08367 0.98193 0 1.57345 0.15912 1.27702 0.12913 0.75717 0.10709 0.61452 0.08691 59315.486825 0.000498 0.47262 0.08217 0.98837 0 1.52403 0.15412 1.24529 0.12592 0.72028 0.10187 0.58922 0.08333 59315.487968 0.000645 0.34441 0.05717 0.96413 0 1.64136 0.13896 1.33790 0.11325 0.56530 0.08072 0.46191 0.06595 59315.489091 0.000477 0.51907 0.08637 0.96809 0 1.67247 0.16455 1.35085 0.13289 0.86814 0.11650 0.69965 0.09389
