/* ** ** 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 59071.053397 0.000344 0.31254 0.05127 0.98319 0 3.19166 0.25667 2.71206 0.21810 0.99751 0.14264 0.84773 0.12122 59071.054039 0.000298 0.35467 0.05856 0.98058 0 3.31156 0.28219 2.79522 0.23819 1.17451 0.16611 0.99175 0.14025 59071.054714 0.000376 0.25804 0.04131 0.99231 0 3.52206 0.25910 2.99444 0.22029 0.90884 0.12924 0.77268 0.10988 59071.055567 0.000477 0.21656 0.03424 0.98182 0 3.32263 0.22429 2.82821 0.19092 0.71956 0.10289 0.61225 0.08755 59071.056516 0.000472 0.21698 0.03461 0.98160 0 3.34062 0.22448 2.82920 0.19008 0.72484 0.10484 0.61376 0.08875 59071.057332 0.000344 0.29486 0.04788 0.95798 0 3.46970 0.26690 2.95025 0.22694 1.02307 0.14629 0.87004 0.12441 59071.058154 0.000477 0.20799 0.03281 0.98182 0 3.47777 0.23181 2.94416 0.19624 0.72334 0.10343 0.61225 0.08755 59071.059092 0.000454 0.21266 0.03405 0.97452 0 3.53058 0.23656 3.00277 0.20119 0.75080 0.10917 0.63863 0.09286 59071.059858 0.000312 0.33348 0.05497 0.98148 0 3.31675 0.27658 2.82060 0.23521 1.10606 0.15728 0.94033 0.13372 59071.060533 0.000362 0.27626 0.04429 0.97600 0 3.56779 0.26855 2.99745 0.22559 0.98563 0.13951 0.82940 0.11741 59071.061213 0.000318 0.33034 0.05399 0.97273 0 3.33277 0.27308 2.83456 0.23226 1.10095 0.15570 0.93614 0.13239 59071.062002 0.000472 0.25671 0.03973 0.95092 0 3.20111 0.22683 2.71981 0.19272 0.82174 0.11306 0.69818 0.09606
