/* ** ** 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 58641.989388 0.000367 0.20134 0.04999 0.96063 0 1.87166 0.18854 1.60993 0.16218 0.37684 0.08551 0.32418 0.07356 58641.990219 0.000463 0.17595 0.04338 0.95625 0 1.72366 0.16635 1.46828 0.14168 0.30328 0.06881 0.25850 0.05865 58641.991391 0.000709 0.11354 0.02720 0.96327 0 1.75237 0.13450 1.47836 0.11345 0.19896 0.04516 0.16759 0.03803 58641.992432 0.000333 0.21716 0.05474 0.99130 0 1.86992 0.20546 1.58931 0.17460 0.40606 0.09213 0.34693 0.07872 58641.993332 0.000567 0.13318 0.03214 0.96939 0 1.84760 0.15199 1.56405 0.12864 0.24607 0.05583 0.20816 0.04723 58641.994307 0.000408 0.17626 0.04345 0.97872 0 1.93492 0.18634 1.61846 0.15585 0.34105 0.07740 0.28660 0.06503 58641.995074 0.000359 0.26718 0.06845 0.97581 0 1.44526 0.17204 1.21973 0.14521 0.38614 0.08761 0.32686 0.07417 58641.995942 0.000509 0.14597 0.03593 0.95455 0 1.90386 0.16565 1.59445 0.13872 0.27791 0.06400 0.23234 0.05351 58641.996906 0.000454 0.16750 0.04055 0.98726 0 1.83054 0.16979 1.54503 0.14329 0.30662 0.06857 0.25849 0.05780 58641.997889 0.000530 0.15342 0.03741 0.96721 0 1.71013 0.15283 1.45351 0.12987 0.26236 0.05953 0.22345 0.05070 58641.999209 0.000790 0.18082 0.03410 0.98901 0 1.61884 0.12142 1.38153 0.10361 0.29272 0.05064 0.25036 0.04331
