/* ** ** 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 56742.193596 0.000608 0.29997 0.02463 0.98571 0 6.99454 0.27484 6.34759 0.24941 2.09815 0.15129 1.90570 0.13741 56742.194803 0.000599 0.28565 0.02330 0.98068 0 7.49578 0.28533 6.81967 0.25959 2.14116 0.15449 1.94804 0.14056 56742.196105 0.000703 0.28434 0.02297 0.98765 0 6.41792 0.24504 5.84084 0.22301 1.82490 0.12988 1.66085 0.11820 56742.197474 0.000666 0.26130 0.02097 0.98696 0 7.38542 0.26978 6.71912 0.24544 1.92980 0.13789 1.75571 0.12545 56742.198802 0.000663 0.27097 0.02202 0.99127 0 7.04827 0.26425 6.41336 0.24045 1.90988 0.13771 1.73779 0.12530 56742.200136 0.000671 0.25789 0.02082 0.98707 0 7.33997 0.26674 6.67994 0.24275 1.89291 0.13649 1.72262 0.12421 56742.201470 0.000663 0.26095 0.02104 0.98253 0 7.42382 0.27159 6.73535 0.24641 1.93722 0.13923 1.75783 0.12633 56742.202734 0.000602 0.30940 0.02516 0.99038 0 6.90682 0.27380 6.28530 0.24916 2.13695 0.15171 1.94470 0.13806 56742.204091 0.000755 0.30562 0.02212 0.99234 0 7.03497 0.24752 6.40151 0.22523 2.14999 0.13602 1.95647 0.12377
