/* ** ** 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 56042.394450 0.000327 0.26293 0.04213 0.97345 0 5.32371 0.38670 3.48980 0.25297 1.39975 0.19992 0.91463 0.13032 56042.395844 0.001068 0.31356 0.02582 0.96477 0 4.68818 0.18516 3.55211 0.14022 1.47000 0.10622 1.10771 0.08000 56042.398009 0.001097 0.27585 0.02221 0.97361 0 5.11632 0.19113 3.90826 0.14599 1.41135 0.10068 1.07736 0.07686 56042.399464 0.000359 0.21904 0.03436 0.95968 0 5.01175 0.33118 3.82412 0.25269 1.09777 0.15617 0.83736 0.11912 56042.400176 0.000353 0.26313 0.04315 0.95082 0 4.17807 0.30715 3.17980 0.23376 1.09936 0.16113 0.83659 0.12261 56042.401634 0.001105 0.27699 0.02245 0.97644 0 5.02667 0.18928 3.82989 0.14418 1.39234 0.09993 1.06022 0.07608 56042.404126 0.001386 0.27764 0.02064 0.97286 0 4.76440 0.16402 3.62917 0.12494 1.32280 0.08715 1.00865 0.06644
