/* ** ** 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 57608.918063 0.000304 0.21731 0.05415 0.96190 0 4.99637 0.52731 1.78590 0.18709 1.08575 0.24510 0.39670 0.08870 57608.918786 0.000420 0.19202 0.04715 0.97241 0 4.75057 0.47841 1.50496 0.15147 0.91220 0.20427 0.28416 0.06354 57608.919588 0.000382 0.22269 0.05531 0.96970 0 4.73621 0.51199 1.40161 0.15153 1.05472 0.23585 0.31302 0.06999 57608.920479 0.000509 0.20133 0.04951 0.96591 0 3.95907 0.40471 1.17735 0.12036 0.79708 0.17827 0.23569 0.05270 57608.921642 0.000654 0.13366 0.03193 0.96460 0 4.63103 0.38863 1.37688 0.11555 0.61899 0.13842 0.18379 0.04110 57608.922681 0.000385 0.25135 0.06463 0.93233 0 4.27481 0.48997 1.25551 0.14390 1.07448 0.24732 0.31480 0.07249 57608.923561 0.000495 0.17899 0.04364 0.95322 0 4.60845 0.44725 1.37616 0.13357 0.82488 0.18448 0.24581 0.05496 57608.924544 0.000489 0.17450 0.04295 0.96450 0 4.71169 0.44859 1.38553 0.13194 0.82220 0.18663 0.24264 0.05506 57608.925363 0.000330 0.29204 0.07627 0.96491 0 4.09275 0.50384 1.21303 0.14931 1.19525 0.27528 0.35486 0.08172 57608.926480 0.000787 0.10809 0.02548 0.97059 0 4.78739 0.35641 1.41023 0.10500 0.51746 0.11572 0.15177 0.03394 57608.927721 0.000454 0.19174 0.04750 0.96178 0 4.69504 0.46586 1.36352 0.13531 0.90024 0.20434 0.26193 0.05943 57608.928694 0.000518 0.14614 0.03435 0.98324 0 5.56567 0.48577 1.63516 0.14272 0.81338 0.17750 0.23903 0.05216 57608.929874 0.000663 0.16083 0.03636 0.96070 0 4.55597 0.39054 1.33485 0.11442 0.73274 0.15328 0.21385 0.04473
