/* ** ** 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 58555.321206 0.000472 0.31471 0.05162 0.96933 0 2.29671 0.18375 1.98920 0.15915 0.72279 0.10350 0.62722 0.08978 58555.322117 0.000440 0.30734 0.04998 0.99342 0 2.50542 0.19988 2.17824 0.17378 0.77001 0.10911 0.66956 0.09488 58555.322927 0.000370 0.35094 0.05842 0.99219 0 2.57318 0.22244 2.23548 0.19325 0.90303 0.12848 0.78452 0.11162 58555.323639 0.000341 0.38152 0.06498 0.97458 0 2.57047 0.23008 2.23420 0.19997 0.98068 0.14211 0.85247 0.12353 58555.324420 0.000440 0.31527 0.05138 0.99342 0 2.42141 0.19614 2.10423 0.17045 0.76340 0.10796 0.66335 0.09381 58555.325248 0.000388 0.35012 0.05850 0.98507 0 2.46475 0.21245 2.14429 0.18482 0.86296 0.12353 0.75076 0.10747 58555.326139 0.000503 0.29773 0.04837 0.97701 0 2.26465 0.17768 1.96864 0.15446 0.67424 0.09593 0.58608 0.08339 58555.327218 0.000576 0.37213 0.05313 0.98523 0 2.19918 0.16581 1.91285 0.14422 0.81838 0.09922 0.71188 0.08631 58555.387954 0.000544 0.35648 0.05911 0.97340 0 2.49726 0.21602 1.57929 0.13609 0.89022 0.12593 0.55546 0.07823 58555.388828 0.000330 0.27384 0.06931 0.94737 0 2.43005 0.28786 1.35501 0.16051 0.66545 0.14883 0.37099 0.08296 58555.390043 0.000885 0.36340 0.05084 0.96078 0 2.40445 0.17742 1.34131 0.09898 0.87378 0.10385 0.48707 0.05787
