/* ** ** 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 59734.075989 0.000327 0.34606 0.05767 0.96460 0 8.64507 0.75051 2.64456 0.22956 2.99172 0.42556 0.91426 0.13005 59734.076768 0.000451 0.23261 0.03776 0.97436 0 9.20694 0.67622 2.76685 0.20322 2.14159 0.31004 0.64552 0.09344 59734.077633 0.000414 0.24833 0.04013 0.95804 0 9.64078 0.70820 2.89805 0.21292 2.39410 0.34461 0.71994 0.10360 59734.078539 0.000492 0.21768 0.03419 0.97059 0 9.23581 0.63103 2.79022 0.19064 2.01047 0.28433 0.60707 0.08585 59734.079410 0.000379 0.25755 0.04256 1.00000 0 9.66846 0.74031 2.88902 0.22119 2.49011 0.36463 0.74119 0.10856 59734.080139 0.000350 0.31610 0.05182 0.95868 0 9.17444 0.74764 2.72640 0.22222 2.90005 0.41252 0.85909 0.12220 59734.080830 0.000336 0.28357 0.04644 0.98276 0 10.27213 0.81851 3.05820 0.24367 2.91287 0.41673 0.86968 0.12442 59734.081536 0.000370 0.28633 0.04495 0.95808 0 10.07615 0.75160 3.00322 0.22404 2.88509 0.39851 0.86163 0.11900
