/* ** ** 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 58605.199990 0.000356 0.56217 0.10029 0.98374 0 1.74468 0.18969 1.47451 0.16028 0.98080 0.13871 0.82782 0.11707 58605.200876 0.000530 0.37340 0.05902 0.97431 0 1.95958 0.16309 1.68235 0.14000 0.73171 0.09831 0.62619 0.08413 58605.260467 0.000402 0.37542 0.06256 0.98561 0 2.28441 0.20134 1.94990 0.17184 0.85762 0.12130 0.73114 0.10340 58605.261338 0.000469 0.34125 0.05619 0.99383 0 2.11730 0.17861 1.82233 0.15373 0.72253 0.10218 0.62215 0.08799 58605.262417 0.000611 0.27669 0.04456 0.97156 0 2.04721 0.15429 1.75597 0.13234 0.56643 0.08061 0.48594 0.06915 58605.263470 0.000443 0.42739 0.07300 0.98693 0 1.79515 0.16956 1.54365 0.14580 0.76723 0.10918 0.65972 0.09388 58605.264373 0.000460 0.37609 0.06206 0.99371 0 1.99959 0.17461 1.71947 0.15015 0.75203 0.10531 0.64664 0.09055 58605.265302 0.000469 0.38709 0.06595 0.98765 0 1.84908 0.16805 1.59052 0.14455 0.71577 0.10315 0.61576 0.08873 58605.266205 0.000434 0.38515 0.06539 0.97333 0 2.03786 0.18294 1.75203 0.15728 0.78488 0.11310 0.67481 0.09724 58605.267342 0.000703 0.31369 0.04404 0.98354 0 2.12608 0.14763 1.82261 0.12656 0.66692 0.08139 0.57149 0.06974
