/* ** ** Swift/XRT hardness ratio for Mrk 421. ** 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 56302.341463 0.000396 0.09046 0.01352 0.99270 0 9.08688 0.38910 8.08591 0.34621 0.82202 0.11773 0.72910 0.10442 56302.342268 0.000408 0.09264 0.01370 0.97872 0 8.84862 0.38228 7.84789 0.33902 0.81975 0.11594 0.72585 0.10265 56302.343130 0.000454 0.08313 0.01254 0.98089 0 8.73474 0.36069 7.66595 0.31653 0.72608 0.10531 0.63733 0.09245 56302.344030 0.000440 0.08570 0.01278 0.96711 0 9.01129 0.37268 7.88067 0.32594 0.77225 0.11061 0.67454 0.09661 56302.344846 0.000376 0.10675 0.01607 0.97692 0 8.39977 0.38953 7.31404 0.33918 0.89664 0.12842 0.78077 0.11182 56302.345882 0.000660 0.09406 0.01074 0.99466 0 8.99193 0.30297 7.89643 0.26604 0.84576 0.09228 0.74203 0.08096 56302.408130 0.000408 0.09304 0.01376 0.98582 0 8.83515 0.38237 7.75123 0.33546 0.82206 0.11626 0.72062 0.10191 56302.408842 0.000304 0.12669 0.01949 1.00000 0 8.49114 0.43937 7.37408 0.38157 1.07578 0.15588 0.93553 0.13554 56302.409467 0.000321 0.11798 0.01768 0.97297 0 9.16592 0.44003 8.04399 0.38615 1.08142 0.15348 0.94664 0.13436 56302.410173 0.000385 0.09586 0.01452 0.96992 0 9.11146 0.40306 7.92632 0.35063 0.87339 0.12655 0.76147 0.11032 56302.411009 0.000451 0.08192 0.01233 0.97436 0 9.03082 0.36978 7.88414 0.32282 0.73982 0.10717 0.64625 0.09363 56302.411903 0.000443 0.09021 0.01364 0.99346 0 8.23571 0.35636 7.17972 0.31067 0.74296 0.10762 0.64625 0.09363 56302.412768 0.000422 0.08586 0.01265 0.97260 0 9.49939 0.39394 8.21804 0.34080 0.81564 0.11536 0.70540 0.09976 56302.413651 0.000460 0.08182 0.01248 1.00000 0 8.69474 0.35960 7.57336 0.31321 0.71138 0.10447 0.61822 0.09080 56302.414478 0.000367 0.09764 0.01516 0.98425 0 8.97906 0.40713 7.88985 0.35775 0.87668 0.13017 0.77035 0.11438 56302.415349 0.000503 0.07596 0.01154 0.97126 0 8.65010 0.34186 7.57345 0.29929 0.65704 0.09640 0.57551 0.08441 56302.416585 0.000732 0.09575 0.01057 0.97233 0 8.87475 0.28618 7.74132 0.24962 0.84978 0.08976 0.74134 0.07831
