/* ** ** 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 57649.910396 0.000509 0.17384 0.02661 0.95455 0 4.12760 0.24170 3.43098 0.20091 0.71756 0.10148 0.59623 0.08432 57649.911452 0.000547 0.15801 0.02420 0.98413 0 4.14506 0.23652 3.39119 0.19348 0.65496 0.09309 0.53616 0.07620 57649.912520 0.000521 0.16852 0.02614 0.98333 0 4.04425 0.23844 3.32020 0.19574 0.68152 0.09780 0.55842 0.08015 57649.913452 0.000411 0.19935 0.03107 0.97887 0 4.35991 0.27902 3.59080 0.22980 0.86913 0.12351 0.71744 0.10196 57649.914340 0.000477 0.19481 0.03033 0.99394 0 3.82464 0.24325 3.12907 0.19900 0.74509 0.10589 0.60808 0.08642 57649.915315 0.000498 0.17459 0.02700 0.95930 0 4.18355 0.24778 3.45909 0.20484 0.73039 0.10432 0.60171 0.08594 57649.916406 0.000587 0.14458 0.02242 0.98030 0 4.11628 0.22622 3.40011 0.18684 0.59512 0.08628 0.49225 0.07136 57649.917450 0.000457 0.21155 0.03291 0.96203 0 3.80076 0.24650 3.15862 0.20483 0.80405 0.11370 0.66636 0.09421 57649.918362 0.000454 0.19391 0.03067 0.96178 0 4.02734 0.25467 3.34644 0.21161 0.78094 0.11323 0.64872 0.09404 57649.919817 0.001001 0.17585 0.01943 0.97399 0 3.97734 0.17095 3.27225 0.14064 0.69941 0.07120 0.57532 0.05856
