/* ** ** 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 57872.098792 0.000417 0.22640 0.03574 0.97222 0 4.47852 0.30494 3.16904 0.21562 1.01396 0.14442 0.71176 0.10125 57872.099625 0.000417 0.27655 0.04498 0.96528 0 3.95108 0.29954 2.56925 0.19473 1.09267 0.15725 0.70939 0.10212 57872.100537 0.000495 0.30948 0.05042 0.97076 0 2.96908 0.23565 1.93929 0.15391 0.91889 0.13073 0.60028 0.08539 57872.101552 0.000521 0.23995 0.03865 0.97778 0 3.58160 0.25225 2.32184 0.16353 0.85941 0.12449 0.55730 0.08070 57872.102585 0.000512 0.26127 0.04183 0.96610 0 3.45102 0.25331 2.22838 0.16357 0.90165 0.12827 0.58273 0.08290 57872.103601 0.000503 0.25737 0.04031 0.97126 0 3.64244 0.25961 2.38695 0.17012 0.93744 0.13075 0.61333 0.08554 57872.104671 0.000567 0.23414 0.03707 0.97959 0 3.40333 0.23638 2.21338 0.15372 0.79687 0.11337 0.51899 0.07383 57872.105687 0.000448 0.31865 0.05200 0.97419 0 3.20051 0.26054 2.08757 0.16993 1.01986 0.14424 0.66336 0.09381 57872.106674 0.000538 0.26165 0.04213 0.97312 0 3.20335 0.23645 2.09013 0.15419 0.83814 0.11993 0.54765 0.07837 57872.107834 0.000622 0.21165 0.03338 0.98140 0 3.41835 0.22676 2.22477 0.14757 0.72350 0.10353 0.46979 0.06723 57872.109081 0.000625 0.23764 0.03426 0.95833 0 3.73466 0.23565 2.51499 0.15866 0.88751 0.11504 0.59462 0.07706
