/* ** ** Swift/XRT hardness ratio for M87. ** 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 54417.005240 0.001656 0.22449 0.05568 1.00000 1 0.99975 0.10669 0.31151 0.03321 0.22444 0.05025 0.07018 0.01569 54417.010382 0.003486 0.18576 0.03283 0.99425 1 1.12020 0.07846 0.34486 0.02415 0.20809 0.03377 0.06370 0.01033 54417.075016 0.001540 0.23426 0.06457 0.98113 1 1.37342 0.15904 0.30448 0.03526 0.32174 0.08048 0.07170 0.01798 54417.079243 0.002687 0.13215 0.02947 0.99831 1 1.73546 0.13713 0.37792 0.02987 0.22933 0.04782 0.04981 0.01039 54417.146172 0.001990 0.15549 0.03751 0.97810 1 1.54699 0.14006 0.38092 0.03449 0.24054 0.05379 0.05970 0.01335 54417.149890 0.001729 0.15888 0.03828 0.96639 1 1.76820 0.15878 0.43707 0.03925 0.28092 0.06282 0.06957 0.01556 54417.153231 0.001612 0.20344 0.04661 0.97843 1 1.68454 0.15989 0.41649 0.03953 0.34271 0.07146 0.08471 0.01766 54417.212391 0.001540 0.21251 0.05273 0.98113 1 1.75612 0.18846 0.35911 0.03848 0.37320 0.08348 0.07692 0.01720 54417.215340 0.001409 0.29415 0.07580 1.00000 1 1.39208 0.17829 0.28016 0.03587 0.40948 0.09157 0.08247 0.01844 54417.219131 0.002382 0.13608 0.03096 0.98540 1 1.99309 0.15807 0.40100 0.03180 0.27122 0.05783 0.05445 0.01161 54417.274444 0.001467 0.18366 0.04471 1.00000 1 1.77283 0.17060 0.43200 0.04157 0.32560 0.07281 0.07921 0.01771 54417.277436 0.001525 0.16741 0.04059 0.99048 1 1.88854 0.17689 0.46061 0.04314 0.31616 0.07070 0.07692 0.01720 54417.281489 0.002527 0.16323 0.03183 0.99765 1 1.82147 0.13837 0.43772 0.03325 0.29731 0.05340 0.07143 0.01283 54417.343057 0.001191 0.32874 0.08507 0.97561 1 1.38549 0.18039 0.30257 0.03939 0.45547 0.10186 0.10000 0.02236 54417.347458 0.003210 0.15465 0.02906 1.00000 1 1.76329 0.12479 0.38693 0.02737 0.27270 0.04747 0.05973 0.01040
