/* ** ** 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 55340.879930 0.000321 0.25930 0.04114 0.97297 0 4.33265 0.30958 3.60955 0.25786 1.12347 0.15916 0.93645 0.13264 55340.880581 0.000330 0.23340 0.03666 0.97368 0 4.64654 0.31768 3.86706 0.26438 1.08450 0.15337 0.90240 0.12762 55340.881241 0.000330 0.22032 0.03497 0.95614 0 4.92978 0.32974 4.10597 0.27463 1.08614 0.15633 0.90474 0.13022 55340.881886 0.000315 0.24920 0.03997 0.95413 0 4.63053 0.32786 3.81285 0.26994 1.15393 0.16607 0.94824 0.13648 55340.882598 0.000396 0.26218 0.03659 0.97080 0 4.52887 0.28820 3.75834 0.23917 1.18738 0.14746 0.98637 0.12249 55340.883292 0.000298 0.23319 0.03694 0.98058 0 5.07719 0.35402 4.23089 0.29501 1.18393 0.16841 0.98663 0.14035 55340.883940 0.000350 0.23194 0.03666 0.96694 0 4.42217 0.30471 3.66702 0.25265 1.02569 0.14592 0.85171 0.12115 55340.884669 0.000379 0.21664 0.03419 0.96947 0 4.35568 0.28974 3.59826 0.23931 0.94362 0.13504 0.78058 0.11169 55340.885566 0.000518 0.22693 0.02779 0.97603 0 5.01298 0.26424 4.17140 0.21988 1.13757 0.12575 0.94582 0.10455
