/* ** ** 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 59769.091731 0.000715 0.23378 0.01855 0.97976 0 7.75418 0.26827 7.02477 0.24304 1.81281 0.12948 1.64249 0.11732 59769.093183 0.000738 0.23473 0.01863 0.98039 0 7.50690 0.26006 6.77542 0.23472 1.76212 0.12586 1.58993 0.11356 59769.094584 0.000663 0.25702 0.02051 0.99127 0 7.57986 0.27581 6.86347 0.24974 1.94816 0.13833 1.76452 0.12529 59769.095955 0.000709 0.23096 0.01824 0.97959 0 7.95366 0.27422 7.24303 0.24972 1.83700 0.13055 1.67287 0.11888 59769.097414 0.000749 0.21426 0.01703 0.98456 0 7.96377 0.26892 7.25289 0.24491 1.70634 0.12280 1.55412 0.11185 59769.099433 0.001270 0.25454 0.01482 0.97267 0 7.73292 0.20283 7.04191 0.18470 1.96834 0.10229 1.79245 0.09315
