/* ** ** 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 56005.166502 0.000796 0.31111 0.02552 0.98182 0 6.40598 0.25665 4.70916 0.18815 1.99295 0.14268 1.47234 0.10515 56005.168140 0.000842 0.28321 0.02329 0.98282 0 6.40462 0.24616 4.85135 0.18640 1.81387 0.13184 1.37504 0.09991 56005.169711 0.000729 0.35004 0.02913 0.98810 0 6.05140 0.25825 4.56052 0.19462 2.11825 0.15130 1.59651 0.11401 56005.171256 0.000816 0.30279 0.02494 0.96454 0 6.32849 0.24898 4.78869 0.18839 1.91620 0.13868 1.44614 0.10465 56005.172790 0.000718 0.33141 0.02739 0.97581 0 6.58914 0.27119 4.95101 0.20375 2.18370 0.15648 1.63837 0.11739 56005.174236 0.000729 0.34023 0.02817 0.98810 0 6.22182 0.26070 4.69542 0.19673 2.11683 0.15117 1.59651 0.11401 56005.176001 0.001036 0.34186 0.02410 0.98045 0 6.06849 0.21639 4.54358 0.16201 2.07457 0.12618 1.55219 0.09440
