/* ** ** 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 56025.809769 0.000694 0.36430 0.03042 0.97083 0 5.17560 0.22207 4.66935 0.20035 1.88549 0.13510 1.70102 0.12188 56025.811123 0.000660 0.43998 0.03739 0.98246 0 4.50732 0.21239 4.06538 0.19157 1.98315 0.14023 1.78869 0.12648 56025.812442 0.000660 0.39035 0.03282 0.98246 0 5.08225 0.22655 4.55821 0.20318 1.98385 0.14140 1.78217 0.12703 56025.813814 0.000712 0.38748 0.03282 0.98780 0 4.65452 0.20895 4.20033 0.18856 1.80353 0.12957 1.62746 0.11692 56025.815185 0.000660 0.41034 0.03477 0.98246 0 4.81572 0.22066 4.34312 0.19900 1.97609 0.14085 1.78217 0.12703 56025.816438 0.000593 0.46078 0.03974 0.98049 0 4.78994 0.23389 4.31960 0.21092 2.20711 0.15691 1.99041 0.14150 56025.817680 0.000648 0.40650 0.03471 0.99554 0 4.83608 0.22322 4.36258 0.20136 1.96588 0.14123 1.77342 0.12740 56025.819572 0.001244 0.38633 0.02415 0.98605 0 4.91217 0.16187 4.42367 0.14578 1.89773 0.10078 1.70951 0.09079
