/* ** ** 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 59050.019725 0.000315 0.24205 0.05884 0.97248 0 1.95258 0.20910 1.64640 0.17628 0.47262 0.10314 0.39689 0.08661 59050.020391 0.000350 0.21488 0.04939 0.95868 0 2.18988 0.21166 1.84785 0.17860 0.47056 0.09813 0.39721 0.08282 59050.021062 0.000321 0.20819 0.04997 0.95495 0 2.23475 0.22342 1.90621 0.19058 0.46526 0.10153 0.39689 0.08661 59050.021921 0.000538 0.28342 0.04598 0.97312 0 2.29629 0.17578 1.93069 0.14779 0.65082 0.09309 0.54791 0.07836 59050.022769 0.000310 0.21183 0.05228 0.94393 0 2.19923 0.22967 1.87330 0.19564 0.46587 0.10417 0.39670 0.08870 59050.023576 0.000498 0.32121 0.05277 0.98837 0 2.18955 0.18003 1.82553 0.15009 0.70331 0.10003 0.58629 0.08338 59050.024392 0.000318 0.21124 0.05159 0.97273 0 2.19233 0.22719 1.83499 0.19014 0.46310 0.10241 0.38853 0.08592 59050.025064 0.000353 0.18578 0.04547 0.98361 0 2.14526 0.21357 1.79393 0.17860 0.39854 0.08912 0.33389 0.07466 59050.026027 0.000611 0.25864 0.04108 0.97156 0 2.29219 0.16837 1.91246 0.14047 0.59285 0.08348 0.49596 0.06983 59050.027323 0.000680 0.23798 0.03756 0.97872 0 2.19039 0.15336 1.83282 0.12832 0.52127 0.07372 0.43551 0.06159 59050.028614 0.000611 0.24083 0.03803 0.94787 0 2.49436 0.17511 2.07649 0.14577 0.60073 0.08496 0.50083 0.07083 59050.029551 0.000327 0.18132 0.04414 0.96460 0 2.41556 0.23241 2.03575 0.19585 0.43798 0.09794 0.36758 0.08219 59050.030197 0.000318 0.19385 0.04873 0.97273 0 2.26553 0.22967 1.89266 0.19184 0.43916 0.10103 0.36515 0.08399
