/* ** ** 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 54892.057415 0.000431 0.15447 0.01198 0.99329 0 18.68889 0.52427 17.29937 0.48528 2.88691 0.20865 2.67211 0.19314 54892.058222 0.000376 0.16667 0.01308 0.97692 0 20.33782 0.59365 18.53476 0.54093 3.38977 0.24694 3.08684 0.22480 54892.059029 0.000431 0.13898 0.01069 0.99329 0 21.29742 0.57016 19.19879 0.51398 2.95997 0.21345 2.66830 0.19241 54892.059834 0.000373 0.16950 0.01306 0.99225 0 20.24945 0.59580 18.42230 0.54201 3.43221 0.24450 3.12337 0.22246 54892.060566 0.000359 0.16957 0.01306 0.98387 0 21.19349 0.62087 19.33404 0.56639 3.59386 0.25597 3.27697 0.23340 54892.061330 0.000405 0.14962 0.01152 1.00000 0 21.06654 0.58122 19.20060 0.52970 3.15202 0.22660 2.87175 0.20642 54892.062160 0.000425 0.14230 0.01101 0.98639 0 20.90045 0.56509 19.05615 0.51520 2.97409 0.21555 2.71358 0.19665 54892.063008 0.000422 0.13788 0.01080 0.99315 0 21.37581 0.57473 19.44792 0.52289 2.94721 0.21678 2.68379 0.19740 54892.063835 0.000405 0.14721 0.01144 1.00000 0 21.13172 0.58307 19.12673 0.52772 3.11079 0.22595 2.81451 0.20443 54892.064657 0.000417 0.14706 0.01129 0.99306 0 20.70812 0.56700 18.96166 0.51915 3.04526 0.21846 2.78961 0.20013 54892.065540 0.000466 0.13486 0.01021 0.99379 0 20.08440 0.52638 18.49057 0.48457 2.70867 0.19247 2.49517 0.17730 54892.066405 0.000399 0.15408 0.01187 0.98551 0 20.58345 0.57630 18.92523 0.52981 3.17140 0.22758 2.91432 0.20912 54892.067180 0.000376 0.16308 0.01253 0.99231 0 20.59049 0.59410 18.99385 0.54802 3.35792 0.23917 3.09915 0.22074 54892.068135 0.000579 0.14304 0.00941 0.98000 0 20.99009 0.48298 19.23870 0.44264 3.00238 0.18507 2.75363 0.16968
