/* ** ** 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 58166.823189 0.000399 0.17490 0.04305 0.97101 0 2.03227 0.19342 1.69322 0.16112 0.35545 0.08068 0.29505 0.06698 58166.823984 0.000396 0.15539 0.03745 1.00000 0 2.23423 0.20064 1.87890 0.16871 0.34718 0.07764 0.29246 0.06540 58166.824766 0.000385 0.19857 0.04276 0.98496 0 2.35961 0.20970 2.00242 0.17795 0.46856 0.09189 0.39761 0.07798 58166.825492 0.000341 0.17374 0.04244 0.97458 0 2.36182 0.23212 2.00499 0.19705 0.41035 0.09176 0.34841 0.07791 58166.826183 0.000350 0.17099 0.04263 0.97521 0 2.27444 0.21625 1.93324 0.18381 0.38891 0.08964 0.33056 0.07619 58166.827008 0.000475 0.13651 0.03263 0.98780 0 2.13175 0.18000 1.81166 0.15297 0.29101 0.06507 0.24733 0.05530 58166.827807 0.000324 0.17190 0.04226 0.99107 0 2.43786 0.22994 2.07199 0.19543 0.41907 0.09513 0.35618 0.08085 58166.828437 0.000307 0.22544 0.05663 0.95283 0 2.04289 0.21972 1.73646 0.18676 0.46054 0.10454 0.39145 0.08886 58166.829065 0.000321 0.23903 0.05961 0.95495 0 1.86053 0.20542 1.58144 0.17460 0.44472 0.09944 0.37799 0.08452 58166.829763 0.000376 0.17463 0.04358 0.97692 0 2.06940 0.19785 1.75869 0.16814 0.36137 0.08329 0.30714 0.07079 58166.830527 0.000388 0.16241 0.03921 0.97015 0 2.23258 0.20309 1.89773 0.17263 0.36259 0.08108 0.30821 0.06892 58166.831331 0.000417 0.15382 0.03703 0.98611 0 2.15917 0.19273 1.83410 0.16371 0.33212 0.07427 0.28216 0.06309 58166.832268 0.000521 0.12927 0.03079 0.98333 0 2.05943 0.16883 1.75111 0.14355 0.26623 0.05953 0.22637 0.05062 58166.833218 0.000428 0.15981 0.03853 0.97973 0 2.03381 0.18350 1.72905 0.15600 0.32503 0.07268 0.27632 0.06179 58166.833947 0.000301 0.19322 0.04730 0.97115 0 2.41458 0.24049 2.05333 0.20451 0.46655 0.10432 0.39670 0.08870 58166.834823 0.000576 0.19621 0.03534 0.98995 0 2.25504 0.16595 1.91766 0.14112 0.44247 0.07274 0.37626 0.06186
