/* ** ** 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 56782.067231 0.000938 0.29199 0.02391 0.96914 0 7.72967 0.29806 4.31056 0.16616 2.25695 0.16300 1.25904 0.09088 56782.069057 0.000888 0.30669 0.02512 0.96417 0 7.95039 0.31184 4.35720 0.17091 2.43830 0.17529 1.33591 0.09604 56782.070857 0.000911 0.29598 0.02415 0.97460 0 7.94924 0.30892 4.38630 0.17045 2.35278 0.16884 1.29768 0.09312 56782.072564 0.000796 0.30446 0.02488 0.97455 0 8.84210 0.34726 4.86218 0.19094 2.69205 0.19289 1.47939 0.10600 56782.074254 0.000894 0.28423 0.02355 0.97735 0 8.29468 0.31953 4.52912 0.17446 2.35756 0.17295 1.28855 0.09452 56782.076791 0.001644 0.30204 0.01808 0.98592 0 8.03125 0.23219 4.39503 0.12705 2.42574 0.12717 1.32997 0.06971
