/* ** ** 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 58309.488448 0.000420 0.20167 0.05003 0.93103 0 1.80595 0.18115 1.45585 0.14603 0.36420 0.08264 0.29303 0.06647 58309.489354 0.000486 0.19245 0.04710 0.95833 0 1.59490 0.15869 1.29248 0.12857 0.30694 0.06864 0.24886 0.05565 58309.490239 0.000399 0.21497 0.05378 0.97101 0 1.68625 0.17788 1.37340 0.14488 0.36250 0.08223 0.29522 0.06697 58309.490942 0.000304 0.23560 0.05967 0.98095 0 2.00173 0.22541 1.63070 0.18363 0.47161 0.10698 0.38407 0.08712 58309.491796 0.000550 0.12526 0.02978 0.99474 0 2.07971 0.16805 1.69389 0.13687 0.26050 0.05825 0.21199 0.04740 58309.492840 0.000495 0.14954 0.03690 0.96491 0 1.94267 0.17266 1.58336 0.14072 0.29050 0.06686 0.23668 0.05447 58309.493972 0.000637 0.12274 0.02990 0.96364 0 1.83960 0.14686 1.50222 0.11992 0.22578 0.05196 0.18421 0.04240 58309.495068 0.000460 0.19392 0.04872 0.97484 0 1.59428 0.16055 1.29868 0.13078 0.30916 0.07116 0.25195 0.05799 58309.496009 0.000480 0.18930 0.04622 0.97590 0 1.60127 0.15698 1.30557 0.12799 0.30313 0.06778 0.24733 0.05530 58309.497198 0.000709 0.12199 0.02830 0.97959 0 1.80401 0.13881 1.47014 0.11312 0.22008 0.04817 0.17941 0.03927
