/* ** ** 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 59042.053290 0.000477 0.24545 0.03874 0.96970 0 2.97912 0.20884 2.54538 0.17843 0.73124 0.10342 0.62604 0.08854 59042.054303 0.000535 0.21829 0.03423 0.97838 0 2.93007 0.19852 2.53525 0.17177 0.63960 0.09045 0.55341 0.07826 59042.055420 0.000582 0.19929 0.03167 0.97015 0 2.91526 0.19028 2.52328 0.16469 0.58099 0.08417 0.50285 0.07285 59042.056577 0.000576 0.20666 0.03236 0.96482 0 2.91146 0.19033 2.51227 0.16423 0.60168 0.08560 0.51895 0.07383 59042.057703 0.000550 0.22321 0.03573 0.93684 0 2.85774 0.19477 2.46780 0.16820 0.63789 0.09240 0.55088 0.07980 59042.058745 0.000492 0.23813 0.03757 0.98824 0 2.93906 0.20555 2.51144 0.17562 0.69988 0.09899 0.59623 0.08432 59042.059737 0.000501 0.22657 0.03565 0.95376 0 3.09445 0.20792 2.66838 0.17929 0.70111 0.09975 0.60387 0.08591 59042.060692 0.000454 0.23197 0.03645 0.98089 0 3.25319 0.22268 2.80232 0.19181 0.75463 0.10673 0.65043 0.09199 59042.061844 0.000697 0.19467 0.02751 0.97598 0 3.06964 0.17511 2.64250 0.15074 0.59756 0.07726 0.51506 0.06660 59042.974192 0.000611 0.18955 0.02921 0.96682 0 3.04127 0.18618 2.59242 0.15869 0.57647 0.08153 0.49101 0.06944 59042.975575 0.000773 0.30132 0.03800 0.97004 0 2.52503 0.15256 2.13744 0.12912 0.76084 0.08421 0.64161 0.07101
