/* ** ** 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 57522.445170 0.000304 0.25731 0.04108 1.00000 0 4.26712 0.30897 3.68456 0.26677 1.09796 0.15625 0.94884 0.13501 57522.445867 0.000388 0.18939 0.02961 1.00000 0 4.51190 0.28348 3.90107 0.24509 0.85450 0.12233 0.73947 0.10587 57522.446617 0.000362 0.21876 0.03412 0.96000 0 4.38688 0.28867 3.81628 0.25112 0.95968 0.13572 0.83472 0.11805 57522.447349 0.000370 0.20752 0.03278 0.97656 0 4.37591 0.28356 3.79922 0.24619 0.90808 0.13081 0.78840 0.11357 57522.448063 0.000344 0.21937 0.03395 0.96639 0 4.66468 0.30748 4.04991 0.26696 1.02330 0.14329 0.88844 0.12441 57522.448813 0.000405 0.17355 0.02695 0.99286 0 4.73100 0.28470 4.10755 0.24718 0.82105 0.11755 0.71287 0.10206 57522.449623 0.000405 0.20959 0.03354 0.95714 0 3.99039 0.26290 3.47078 0.22866 0.83636 0.12198 0.72741 0.10610 57522.450381 0.000353 0.22106 0.03455 0.96721 0 4.42070 0.29422 3.84030 0.25559 0.97725 0.13820 0.84887 0.12005 57522.451136 0.000402 0.19166 0.02998 0.98561 0 4.34368 0.27388 3.77444 0.23798 0.83252 0.11919 0.72328 0.10355 57522.451915 0.000376 0.22629 0.03590 0.98462 0 3.93894 0.26917 3.42063 0.23375 0.89133 0.12761 0.77413 0.11083 57522.452644 0.000353 0.21244 0.03302 0.99180 0 4.55440 0.29891 3.95362 0.25948 0.96756 0.13630 0.83993 0.11832 57522.453315 0.000318 0.23464 0.03681 0.96364 0 4.66962 0.31719 4.02721 0.27354 1.09568 0.15496 0.94497 0.13364 57522.454056 0.000422 0.17069 0.02613 0.97945 0 4.72708 0.27684 4.10367 0.24033 0.80688 0.11411 0.70047 0.09906 57522.454907 0.000428 0.19567 0.03026 0.97297 0 4.08847 0.25585 3.55608 0.22254 0.79998 0.11313 0.69560 0.09837 57522.455795 0.000460 0.21173 0.03003 1.00000 0 4.15625 0.24779 3.61414 0.21547 0.87999 0.11324 0.76519 0.09846
