/* ** ** Swift/XRT hardness ratio for Mrk 501. ** 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 59427.988307 0.000362 0.26904 0.04296 0.98400 0 3.53752 0.26224 3.02744 0.22439 0.95172 0.13460 0.81436 0.11517 59427.989224 0.000556 0.15884 0.02434 0.95833 0 3.97083 0.22607 3.40885 0.19408 0.63074 0.08973 0.54155 0.07704 59427.990216 0.000437 0.18947 0.02936 0.98675 0 4.13126 0.26173 3.53593 0.22401 0.78276 0.11070 0.67226 0.09507 59427.991026 0.000373 0.22152 0.03462 0.96899 0 4.24894 0.28262 3.62030 0.24078 0.94121 0.13311 0.80133 0.11333 59427.991877 0.000477 0.20836 0.03275 0.96970 0 3.46337 0.22535 2.97172 0.19333 0.72163 0.10327 0.61953 0.08866 59427.992826 0.000472 0.21648 0.03444 0.97546 0 3.32620 0.22513 2.86499 0.19391 0.72007 0.10366 0.62014 0.08927 59427.993674 0.000376 0.24305 0.03881 0.98462 0 3.75279 0.26575 3.18683 0.22566 0.91212 0.13056 0.77441 0.11082 59427.994580 0.000530 0.15934 0.02434 0.98361 0 4.10482 0.23666 3.49562 0.20154 0.65407 0.09251 0.55648 0.07870 59427.995575 0.000466 0.18453 0.02864 0.98137 0 4.02593 0.24987 3.42295 0.21241 0.74289 0.10570 0.63067 0.08972 59427.996507 0.000466 0.20137 0.03152 0.99379 0 3.62510 0.23661 3.09162 0.20179 0.72999 0.10385 0.62278 0.08860 59427.997430 0.000457 0.21147 0.03338 0.95570 0 3.85299 0.26366 3.25401 0.22268 0.81479 0.11591 0.68881 0.09798
