/* ** ** 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 54995.941491 0.001076 0.25300 0.02020 0.98118 0 4.85637 0.17338 4.30266 0.15360 1.22868 0.08773 1.08929 0.07777 54995.943594 0.001027 0.26355 0.02136 0.96620 0 4.94684 0.18087 4.35682 0.15929 1.30373 0.09430 1.14721 0.08298 54995.945576 0.000955 0.28454 0.02316 0.97879 0 4.85647 0.18545 4.30336 0.16432 1.38185 0.09931 1.22459 0.08800 54995.947550 0.001019 0.26437 0.02112 0.96307 0 5.00844 0.18160 4.44887 0.16131 1.32406 0.09423 1.17586 0.08368 54995.949468 0.000900 0.29414 0.02383 0.98392 0 4.99442 0.19289 4.43964 0.17146 1.46904 0.10462 1.30587 0.09300 54995.952240 0.001872 0.27089 0.01580 0.97991 0 4.99787 0.13444 4.41147 0.11866 1.35386 0.07005 1.19265 0.06170
