/* ** ** 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 56754.464357 0.000712 0.24925 0.02008 0.98374 0 7.19897 0.25775 6.53792 0.23406 1.79437 0.12950 1.62907 0.11757 56754.465758 0.000689 0.28100 0.02300 0.99160 0 6.49420 0.24779 5.92859 0.22621 1.82484 0.13216 1.66595 0.12065 56754.467043 0.000596 0.31654 0.02601 0.98058 0 6.84066 0.27416 6.20974 0.24888 2.16535 0.15533 1.96688 0.14110 56754.468374 0.000735 0.27176 0.02195 0.98031 0 6.44207 0.23989 5.86557 0.21842 1.75070 0.12549 1.59188 0.11411 56754.469728 0.000619 0.30492 0.02507 0.99065 0 6.69649 0.26658 6.11495 0.24343 2.04186 0.14686 1.86466 0.13412 56754.471013 0.000666 0.27537 0.02214 0.98696 0 7.01395 0.26119 6.38718 0.23784 1.93143 0.13762 1.75971 0.12539 56754.472306 0.000628 0.29787 0.02409 0.97696 0 6.97128 0.26967 6.34666 0.24551 2.07656 0.14747 1.88928 0.13416 56754.473952 0.001019 0.31993 0.02011 0.98580 0 6.73694 0.20744 6.14226 0.18912 2.15532 0.11812 1.96399 0.10763
