/* ** ** 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 59398.073652 0.000365 0.23617 0.03375 0.99206 0 4.59777 0.28826 4.17932 0.26199 1.08587 0.13945 0.98519 0.12648 59398.074346 0.000330 0.23717 0.03790 0.97368 0 4.14322 0.29291 3.76461 0.26613 0.98265 0.14084 0.89287 0.12798 59398.075489 0.000813 0.23983 0.02313 0.97153 0 4.58167 0.19457 4.12996 0.17534 1.09881 0.09516 0.99024 0.08575 59398.076641 0.000339 0.24652 0.03773 0.96581 0 4.52594 0.30616 3.93226 0.26600 1.11573 0.15318 0.96934 0.13308 59398.077387 0.000408 0.19446 0.03005 0.97163 0 4.32242 0.26898 3.75997 0.23398 0.84055 0.11887 0.73114 0.10340 59398.078122 0.000327 0.24324 0.03868 0.93805 0 4.41566 0.30608 3.84479 0.26651 1.07405 0.15374 0.93497 0.13383 59398.079523 0.001073 0.27382 0.02220 0.98652 0 4.41404 0.16614 3.95980 0.14902 1.20864 0.08681 1.08431 0.07788 59398.080967 0.000370 0.24152 0.03871 0.96875 0 3.78517 0.26626 3.29150 0.23153 0.91418 0.13165 0.79493 0.11448 59398.081679 0.000341 0.22978 0.03654 0.98305 0 4.28044 0.29635 3.71868 0.25745 0.98355 0.14078 0.85434 0.12229 59398.082344 0.000324 0.23657 0.03777 0.98214 0 4.37893 0.30960 3.80720 0.26918 1.03591 0.14828 0.90094 0.12896 59398.083007 0.000339 0.25203 0.03997 0.97436 0 4.02436 0.28867 3.48795 0.25019 1.01425 0.14344 0.87866 0.12426 59398.083655 0.000310 0.26481 0.04249 0.94393 0 4.28192 0.31022 3.69963 0.26803 1.13390 0.16232 0.98122 0.14045
