/* ** ** Swift/XRT hardness ratio for 3C 279. ** 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 54688.434229 0.001467 0.49696 0.13578 0.97030 1 0.20332 0.03192 0.16484 0.02588 0.10104 0.02260 0.08163 0.01825 54688.437512 0.001816 0.49646 0.13707 0.97600 1 0.16182 0.02566 0.13082 0.02074 0.08034 0.01816 0.06491 0.01467 54688.443612 0.004285 0.34879 0.06584 0.98454 1 0.18603 0.01781 0.14940 0.01430 0.06489 0.01056 0.05220 0.00849 54688.539236 0.036035 0.44722 0.11576 0.05037 1 0.20271 0.02945 0.15775 0.02292 0.09066 0.01942 0.07010 0.01502 54688.578597 0.003326 0.45916 0.09022 0.98536 1 0.19029 0.02110 0.14679 0.01627 0.08737 0.01418 0.06736 0.01093 54688.645166 0.003443 0.33654 0.06898 0.98627 1 0.20234 0.02099 0.16280 0.01688 0.06809 0.01204 0.05476 0.00968 54688.713307 0.002644 0.46487 0.09281 0.97461 1 0.22471 0.02545 0.17942 0.02032 0.10446 0.01717 0.08344 0.01372
