/* ** ** 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 59808.954535 0.000787 0.19467 0.01864 0.98162 0 5.59013 0.21578 5.08502 0.19627 1.08824 0.09533 0.98996 0.08671 59808.956372 0.001050 0.19903 0.01556 0.97521 0 6.18723 0.19678 5.64524 0.17954 1.23144 0.08796 1.12283 0.08020 59808.958459 0.001036 0.19766 0.01563 0.98324 0 6.23161 0.19963 5.69422 0.18241 1.23177 0.08902 1.12552 0.08134 59808.959796 0.000301 0.16956 0.02605 0.99038 0 6.33642 0.37311 5.78927 0.34089 1.07442 0.15245 0.98164 0.13928 59808.961048 0.000952 0.21260 0.01690 0.99392 0 6.22205 0.20684 5.68542 0.18901 1.32279 0.09552 1.20868 0.08728 59808.963291 0.001291 0.20756 0.01429 0.98879 0 6.22316 0.17827 5.68632 0.16289 1.29170 0.08088 1.18029 0.07391
