/* ** ** 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 55752.790320 0.000327 0.27727 0.04498 0.97345 0 3.93643 0.30042 3.25032 0.24800 1.09145 0.15622 0.90115 0.12895 55752.791050 0.000402 0.26766 0.03743 0.94245 0 4.49625 0.28527 3.69412 0.23437 1.20345 0.14997 0.99005 0.12336 55752.791773 0.000321 0.26124 0.04275 0.99099 0 4.18750 0.31207 3.40197 0.25351 1.09393 0.15938 0.88698 0.12921 55752.792890 0.000796 0.25277 0.02445 0.97818 0 4.86861 0.21201 3.94612 0.17184 1.23065 0.10632 0.99794 0.08621 55752.794713 0.001027 0.30893 0.02521 0.97183 0 4.59263 0.18195 3.73229 0.14786 1.41878 0.10122 1.15231 0.08220 55752.796142 0.000402 0.27121 0.03703 1.00000 0 4.48879 0.28913 3.66111 0.23582 1.21740 0.14657 0.99446 0.11972 55752.796842 0.000298 0.25353 0.04064 0.98058 0 4.81914 0.34814 3.87071 0.27962 1.22178 0.17483 0.98145 0.14044 55752.797447 0.000307 0.23709 0.03779 0.99057 0 4.92578 0.34581 3.99079 0.28015 1.16785 0.16711 0.94407 0.13509 55752.798182 0.000428 0.26088 0.03529 0.96517 0 4.64663 0.28849 3.77237 0.23420 1.21220 0.14566 0.98482 0.11834
