/* ** ** 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 57262.170719 0.000457 0.23848 0.03035 0.96629 0 4.88335 0.27202 4.22261 0.23520 1.16456 0.13325 1.00679 0.11519 57262.171717 0.000523 0.19909 0.04867 0.97222 1 4.62055 0.45651 1.14744 0.11337 0.91990 0.20570 0.22857 0.05111 57262.172850 0.000610 0.19335 0.04736 1.00000 1 4.00309 0.40007 0.98657 0.09859 0.77398 0.17308 0.19048 0.04259 57262.173983 0.000523 0.24381 0.06050 0.91667 1 4.03133 0.43367 0.99737 0.10727 0.98290 0.21980 0.24242 0.05421 57262.175086 0.000581 0.25601 0.05760 0.97086 1 4.07810 0.42036 1.00569 0.10366 1.04404 0.20881 0.25750 0.05150 57262.237061 0.000113 0.20543 0.06864 0.95177 0 3.46689 0.48140 3.01221 0.41827 0.71222 0.21645 0.61881 0.18806 57262.237771 0.000581 0.23181 0.05659 0.97500 1 3.75942 0.39888 0.92291 0.09792 0.87148 0.19160 0.21389 0.04702 57262.238904 0.000552 0.17921 0.04459 0.97368 1 4.85172 0.47247 1.18082 0.11499 0.86949 0.19906 0.21151 0.04842 57262.239761 0.000305 0.36401 0.09582 0.95238 1 4.45043 0.60531 1.09129 0.14841 1.62001 0.36513 0.39710 0.08949 57262.240647 0.000581 0.25894 0.06530 0.92500 1 3.43221 0.38828 0.83293 0.09422 0.88874 0.20029 0.21465 0.04837 57262.241707 0.000479 0.21197 0.05277 1.00000 1 4.67393 0.49407 1.13548 0.12001 0.99073 0.22328 0.24066 0.05424 57262.242608 0.000421 0.28501 0.07345 1.00000 1 3.93330 0.49142 0.95651 0.11950 1.12102 0.25269 0.27386 0.06172 57262.243726 0.000697 0.25044 0.05340 0.98343 1 3.85467 0.37230 0.94516 0.09128 0.96538 0.18351 0.23603 0.04486
