/* ** ** 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 58709.266579 0.000336 0.24361 0.05950 0.98276 0 1.78647 0.19591 1.50795 0.16535 0.43521 0.09497 0.36904 0.08053 58709.267212 0.000298 0.29233 0.07612 0.98058 0 1.58602 0.20323 1.33948 0.17162 0.46364 0.10510 0.39187 0.08884 58709.268147 0.000637 0.25119 0.04022 0.98636 0 2.15085 0.15834 1.82907 0.13465 0.54027 0.07683 0.45935 0.06532 58709.269096 0.000312 0.21038 0.05196 0.99074 0 2.09468 0.21969 1.77992 0.18668 0.44067 0.09854 0.37446 0.08373 58709.269773 0.000365 0.15475 0.03778 0.97619 0 2.44444 0.22139 2.07996 0.18838 0.37829 0.08576 0.32178 0.07295 58709.270522 0.000385 0.18240 0.04516 0.96241 0 2.00742 0.19980 1.69664 0.16886 0.36616 0.08300 0.30921 0.07010 58709.271257 0.000350 0.18497 0.04588 0.97521 0 2.13252 0.21459 1.81455 0.18259 0.39446 0.08942 0.33542 0.07604 58709.271966 0.000359 0.19877 0.04889 0.97581 0 1.96033 0.20089 1.66597 0.17072 0.38965 0.08713 0.33113 0.07404 58709.272684 0.000359 0.23487 0.05959 0.98387 0 1.62381 0.18498 1.38112 0.15734 0.38139 0.08645 0.32442 0.07354 58709.273425 0.000382 0.15944 0.03957 0.99242 0 2.22564 0.20789 1.87598 0.17518 0.35487 0.08159 0.29841 0.06859 58709.274278 0.000472 0.16502 0.03999 0.98160 0 1.79409 0.16750 1.51603 0.14152 0.29607 0.06620 0.25042 0.05599 58709.275149 0.000399 0.16525 0.04097 0.97101 0 2.09661 0.19500 1.77261 0.16485 0.34647 0.07963 0.29173 0.06706 58709.275893 0.000344 0.19060 0.04733 0.98319 0 2.11291 0.21435 1.77611 0.18013 0.40272 0.09129 0.33828 0.07669 58709.276645 0.000408 0.22525 0.05264 0.96454 0 1.79000 0.17874 1.52169 0.15195 0.40319 0.08520 0.34278 0.07243
