/* ** ** 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 57924.246524 0.001118 0.28507 0.07241 0.98701 1 1.46222 0.17621 0.36845 0.04439 0.41684 0.09321 0.10526 0.02354 57924.248979 0.001336 0.20482 0.05046 0.97826 1 1.71269 0.17714 0.43351 0.04484 0.35080 0.07844 0.08889 0.01988 57924.251492 0.001177 0.23309 0.05694 0.98765 1 1.77209 0.18881 0.44848 0.04778 0.41306 0.09080 0.10429 0.02292 57924.254455 0.001787 0.23696 0.05129 0.97235 1 1.48572 0.14066 0.37747 0.03574 0.35206 0.06853 0.08935 0.01739 57924.982637 0.001525 0.17574 0.04302 1.00000 1 1.88787 0.18050 0.43251 0.04134 0.33178 0.07477 0.07565 0.01705 57924.985396 0.001235 0.23327 0.05799 0.98824 1 1.82149 0.19784 0.40682 0.04418 0.42490 0.09502 0.09524 0.02130 57924.989493 0.002862 0.17759 0.03223 0.97582 1 1.88822 0.13566 0.42153 0.03028 0.33532 0.05589 0.07491 0.01248
