/* ** ** 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 58135.525471 0.000492 0.46678 0.06269 0.99412 0 2.45123 0.18778 2.11325 0.16189 1.14417 0.12622 0.98621 0.10878 58135.526319 0.000356 0.34213 0.05656 0.96748 0 2.83831 0.23888 2.44231 0.20554 0.97106 0.13817 0.83723 0.11913 58135.527062 0.000388 0.38582 0.06444 0.97761 0 2.28949 0.20348 1.98175 0.17613 0.88334 0.12492 0.76463 0.10814 58135.527751 0.000301 0.48874 0.08479 0.97115 0 2.34675 0.23288 2.02157 0.20057 1.14695 0.16322 0.98644 0.14036 58135.528437 0.000385 0.36711 0.06098 0.98496 0 2.40802 0.20976 2.08292 0.18144 0.88401 0.12502 0.76463 0.10814 58135.529259 0.000437 0.36364 0.06059 0.98013 0 2.14610 0.18596 1.85147 0.16043 0.78040 0.11106 0.67318 0.09578 58135.530132 0.000437 0.37993 0.06457 0.98013 0 2.02990 0.18026 1.74670 0.15510 0.77122 0.11176 0.66229 0.09599 58135.530954 0.000385 0.38139 0.06489 0.97744 0 2.34367 0.21236 1.98930 0.18026 0.89385 0.12873 0.75813 0.10920 58135.531718 0.000379 0.36039 0.05919 0.96183 0 2.60255 0.22334 2.24967 0.19306 0.93793 0.13134 0.81087 0.11354 58135.532572 0.000475 0.33152 0.05393 0.98171 0 2.22648 0.18110 1.91445 0.15570 0.73812 0.10399 0.63126 0.08892 58135.533402 0.000356 0.38746 0.06661 0.97561 0 2.47113 0.22521 2.09566 0.19100 0.95747 0.13958 0.81236 0.11847 58135.534065 0.000307 0.54489 0.09488 0.97170 0 2.13114 0.22054 1.82003 0.18833 1.16123 0.16262 0.99194 0.13890 58135.534765 0.000394 0.46266 0.07895 0.96324 0 1.99670 0.19394 1.69826 0.16496 0.92379 0.12961 0.78702 0.11043 58135.535618 0.000460 0.45281 0.06969 0.98742 0 2.05783 0.17821 1.76127 0.15250 0.93180 0.11855 0.79705 0.10140
