/* ** ** 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 56056.029533 0.000778 0.32503 0.02689 0.97398 0 5.34803 0.21699 4.63254 0.18796 1.73825 0.12534 1.50554 0.10857 56056.031008 0.000697 0.34251 0.02853 0.98755 0 5.63436 0.23666 4.86305 0.20426 1.92982 0.13880 1.66578 0.11981 56056.032441 0.000735 0.33658 0.02832 0.99213 0 5.35930 0.22579 4.60724 0.19411 1.80384 0.13137 1.55295 0.11310 56056.033980 0.000804 0.30073 0.02476 0.97482 0 5.59918 0.21984 4.82733 0.18954 1.68386 0.12183 1.45172 0.10503 56056.035537 0.000752 0.35724 0.02967 0.97692 0 5.11749 0.21828 4.41497 0.18831 1.82817 0.13031 1.57689 0.11239 56056.036963 0.000674 0.38712 0.03261 0.97854 0 5.23922 0.23201 4.49680 0.19912 2.02823 0.14532 1.73914 0.12459 56056.038948 0.001311 0.34379 0.02169 0.98896 0 5.22952 0.16625 4.49439 0.14287 1.79788 0.09795 1.54414 0.08413
