/* ** ** 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 56372.736954 0.000339 0.39535 0.06247 0.98291 0 2.96034 0.24940 2.49643 0.21031 1.17037 0.15647 0.98477 0.13165 56372.737585 0.000292 0.44635 0.07658 1.00000 0 2.58639 0.24838 2.21166 0.21239 1.15442 0.16412 0.98709 0.14033 56372.738268 0.000391 0.29152 0.04759 0.98519 0 2.97715 0.23080 2.54704 0.19746 0.86789 0.12470 0.74251 0.10669 56372.739003 0.000344 0.35705 0.05473 0.98319 0 3.25096 0.25709 2.78152 0.21996 1.16074 0.15241 0.99311 0.13040 56372.740383 0.001030 0.41327 0.03522 0.98315 0 3.19912 0.14755 2.73751 0.12626 1.32210 0.09473 1.13131 0.08106 56372.741792 0.000379 0.43356 0.06536 0.98473 0 2.66858 0.22286 2.28451 0.19078 1.15699 0.14522 0.99025 0.12429 56372.743250 0.001079 0.42494 0.03605 0.97587 0 3.01517 0.13912 2.57592 0.11885 1.28126 0.09120 1.09427 0.07789 56372.745389 0.001059 0.43625 0.03745 0.96448 0 3.00184 0.14152 2.56816 0.12107 1.30955 0.09395 1.12036 0.08038 56372.746804 0.000356 0.29294 0.04773 0.97561 0 3.30029 0.25819 2.82222 0.22079 0.96679 0.13817 0.82687 0.11818 56372.747513 0.000353 0.31110 0.05098 0.96721 0 3.17462 0.25437 2.70245 0.21653 0.98764 0.14117 0.84089 0.12018 56372.748224 0.000359 0.39533 0.05862 0.98387 0 3.09579 0.24442 2.64859 0.20911 1.22385 0.15361 1.04707 0.13142
