/* ** ** 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 54598.419285 0.000359 0.27326 0.04454 0.98387 0 4.40556 0.32855 3.05998 0.22426 1.20388 0.17447 0.81677 0.11619 54598.420034 0.000391 0.26267 0.03689 0.97037 0 4.75925 0.30325 3.74944 0.23889 1.25009 0.15646 0.98608 0.12342 54598.420775 0.000350 0.24635 0.03949 0.96694 0 4.37027 0.30819 3.41243 0.24065 1.07662 0.15498 0.84279 0.12132 54598.421469 0.000344 0.30425 0.04663 0.96639 0 4.09445 0.30075 3.21770 0.23635 1.24574 0.16758 0.97938 0.13175 54598.422187 0.000373 0.20709 0.03255 0.97674 0 4.90501 0.31650 3.83951 0.24775 1.01577 0.14557 0.79436 0.11384 54598.423000 0.000434 0.18252 0.02839 0.96667 0 4.79562 0.29193 3.73907 0.22761 0.87529 0.12527 0.68363 0.09783 54598.423845 0.000411 0.21692 0.03387 0.98592 0 4.26123 0.28720 3.34757 0.22561 0.92433 0.13018 0.72607 0.10226 54598.424565 0.000310 0.29730 0.04812 0.96262 0 4.13717 0.31951 3.25467 0.25136 1.22999 0.17497 0.96744 0.13762 54598.425607 0.000732 0.26729 0.02741 0.97628 0 4.70952 0.22010 3.69032 0.17247 1.25880 0.11488 0.98708 0.09007 54598.426657 0.000318 0.24408 0.03872 0.97273 0 4.84476 0.34024 3.81492 0.26791 1.18249 0.16822 0.93128 0.13248 54598.427300 0.000324 0.28906 0.04441 0.99107 0 4.37046 0.32190 3.43549 0.25303 1.26332 0.17035 0.99264 0.13385 54598.427983 0.000359 0.21892 0.03459 0.98387 0 4.74975 0.31837 3.71345 0.24889 1.03981 0.14880 0.81251 0.11627 54598.428958 0.000616 0.26702 0.03015 0.97183 0 4.80096 0.24962 3.67505 0.19107 1.28195 0.12851 0.98175 0.09841 54598.430011 0.000437 0.26586 0.03550 0.98675 0 4.74725 0.29142 3.67918 0.22583 1.26209 0.14969 0.97749 0.11592 54598.430899 0.000451 0.27420 0.03656 0.95513 0 4.59797 0.28009 3.55851 0.21674 1.26075 0.14954 0.97749 0.11592 54598.431955 0.000605 0.30948 0.03613 0.91388 0 4.32969 0.24121 3.36874 0.18767 1.33997 0.13749 1.04220 0.10694
