/* ** ** 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 59703.058715 0.000613 0.30717 0.02548 0.99528 0 13.38569 0.53993 6.08987 0.24397 4.11166 0.29802 1.87423 0.13472 59703.060133 0.000804 0.23834 0.01907 0.97842 0 12.29477 0.43225 6.10750 0.21468 2.93027 0.21064 1.45391 0.10451 59703.061655 0.000718 0.25098 0.02030 0.97177 0 13.43219 0.48456 6.51244 0.23491 3.37121 0.24404 1.63228 0.11811 59703.062986 0.000613 0.30637 0.02516 0.98113 0 12.78818 0.50717 6.19908 0.24584 3.91788 0.28168 1.90126 0.13667 59703.064323 0.000723 0.26724 0.02145 0.98400 0 12.44592 0.46061 6.06933 0.22465 3.32609 0.23693 1.62418 0.11569 59703.065735 0.000689 0.25741 0.02087 0.97899 0 13.69091 0.50020 6.56387 0.23980 3.52412 0.25500 1.68833 0.12217 59703.067237 0.000813 0.26883 0.02024 0.98577 0 12.80095 0.44651 6.14092 0.21417 3.44127 0.22957 1.64839 0.10994
