/* ** ** 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 59404.043802 0.000663 0.22590 0.03697 0.94323 0 5.11128 0.35849 1.94896 0.13560 1.15462 0.17072 0.44925 0.06585 59404.044768 0.000304 0.20413 0.05026 0.96190 0 5.92069 0.60936 1.94159 0.19987 1.20860 0.27031 0.39670 0.08870 59404.045596 0.000524 0.32251 0.05443 0.98895 0 5.24981 0.43723 1.68209 0.13994 1.69310 0.24852 0.54212 0.07946 59404.046469 0.000350 0.23314 0.05803 0.95868 0 4.46324 0.48772 1.47123 0.16071 1.04058 0.23271 0.34540 0.07723 59404.047499 0.000680 0.27368 0.04427 0.94894 0 4.96726 0.37424 1.61963 0.12198 1.35946 0.19458 0.44450 0.06361 59404.048677 0.000498 0.38995 0.06547 0.95930 0 4.84015 0.43757 1.56578 0.14147 1.88741 0.26700 0.60707 0.08585 59404.049727 0.000553 0.37607 0.06325 0.98429 0 4.44756 0.39846 1.39841 0.12518 1.67259 0.23806 0.53003 0.07540 59404.050980 0.000694 0.25911 0.04156 0.95833 0 5.18429 0.38295 1.66309 0.12279 1.34332 0.19123 0.43324 0.06163 59404.052187 0.000512 0.21253 0.04032 0.96610 0 5.84372 0.47326 1.88431 0.15253 1.24197 0.21308 0.39832 0.06831 59404.053064 0.000359 0.21394 0.05298 0.95968 0 5.07623 0.52983 1.59354 0.16632 1.08599 0.24388 0.34477 0.07739 59404.054120 0.000697 0.18431 0.03319 0.93361 0 5.50627 0.38809 1.77551 0.12510 1.01488 0.16819 0.32712 0.05421
