/* ** ** 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 57898.147625 0.000437 0.11598 0.02789 0.99338 0 3.02806 0.23883 2.27773 0.17955 0.35119 0.07977 0.26373 0.05982 57898.148423 0.000362 0.17584 0.04280 0.96800 0 2.56415 0.24656 1.87894 0.18066 0.45088 0.10082 0.33113 0.07404 57898.149329 0.000544 0.11860 0.02806 0.94681 0 2.57349 0.19919 1.89951 0.14702 0.30521 0.06825 0.22509 0.05033 57898.150240 0.000367 0.17964 0.04369 0.94488 0 2.50979 0.23998 1.86212 0.17804 0.45086 0.10082 0.33389 0.07466 57898.150946 0.000339 0.17273 0.04202 0.97436 0 2.76354 0.26449 2.02942 0.19422 0.47736 0.10674 0.35146 0.07859 57898.151673 0.000388 0.15569 0.03749 0.97761 0 2.67900 0.23926 1.96465 0.17546 0.41709 0.09327 0.30585 0.06839 57898.152364 0.000304 0.19503 0.04771 0.96190 0 2.73736 0.27156 2.03245 0.20162 0.53388 0.11938 0.39670 0.08870 57898.153102 0.000434 0.19671 0.04059 0.97333 0 2.71075 0.23329 2.00266 0.17232 0.53323 0.10001 0.39445 0.07397 57898.153892 0.000356 0.17008 0.03856 0.98374 0 3.08945 0.27104 2.29215 0.20109 0.52545 0.10986 0.38898 0.08133 57898.154586 0.000339 0.19172 0.04762 0.97436 0 2.47879 0.25091 1.81178 0.18338 0.47522 0.10780 0.34702 0.07872 57898.155333 0.000408 0.17571 0.04277 0.97872 0 2.24522 0.21587 1.65291 0.15892 0.39450 0.08821 0.29034 0.06492 57898.156438 0.000697 0.20056 0.03250 0.95851 0 2.70481 0.18167 1.99196 0.13379 0.54248 0.07999 0.39893 0.05882 57898.157714 0.000579 0.14309 0.02870 0.98500 0 2.74657 0.19540 2.04589 0.14556 0.39300 0.07370 0.29233 0.05482
