/* ** ** 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 56009.428756 0.000608 0.31778 0.02614 0.98095 0 6.80131 0.27481 6.05722 0.24472 2.16130 0.15486 1.92464 0.13791 56009.429896 0.000532 0.37732 0.03194 0.98370 0 6.47441 0.28390 5.77238 0.25308 2.44293 0.17690 2.17839 0.15777 56009.430949 0.000521 0.37349 0.03131 0.98889 0 6.68480 0.29329 5.97885 0.26228 2.49670 0.17832 2.23328 0.15949 56009.432167 0.000697 0.28559 0.02336 0.97095 0 6.62964 0.25281 5.88104 0.22426 1.89336 0.13702 1.68091 0.12165 56009.433423 0.000558 0.33827 0.02836 0.98964 0 6.91472 0.28927 6.08466 0.25454 2.33901 0.16995 2.05885 0.14961 56009.434552 0.000570 0.36292 0.03026 0.98985 0 6.42190 0.27890 5.63251 0.24462 2.33061 0.16590 2.04396 0.14549 56009.435770 0.000648 0.29008 0.02351 0.97321 0 7.07643 0.27085 6.28810 0.24066 2.05273 0.14662 1.82350 0.13023 56009.436962 0.000544 0.39944 0.03410 0.95745 0 6.19765 0.28084 5.47342 0.24802 2.47557 0.17913 2.18518 0.15815 56009.438122 0.000616 0.30866 0.02558 0.98122 0 6.87828 0.27451 6.08126 0.24267 2.12303 0.15418 1.87696 0.13630 56009.439488 0.000749 0.32985 0.02391 0.96911 0 6.93151 0.24849 6.15803 0.22075 2.28638 0.14403 2.03072 0.12791
