/* ** ** 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 57833.086980 0.000503 0.18832 0.01490 0.98851 0 31.71383 1.00255 12.23413 0.38637 5.97242 0.43306 2.29905 0.16646 57833.088016 0.000532 0.18417 0.01502 0.99457 0 31.66054 1.01419 11.41573 0.36567 5.83082 0.43747 2.10049 0.15763 57833.089072 0.000524 0.19444 0.01544 1.00000 0 30.94322 0.99544 11.17679 0.35957 6.01665 0.43669 2.17366 0.15780 57833.090065 0.000469 0.22344 0.01824 0.96914 0 30.97098 1.06405 11.06847 0.38032 6.92015 0.51249 2.47138 0.18301 57833.091060 0.000527 0.18954 0.01542 0.98352 0 31.75445 1.01171 11.39605 0.36306 6.01883 0.45045 2.15862 0.16154 57833.092093 0.000506 0.18993 0.01594 0.99429 0 31.51449 1.02511 11.43075 0.37177 5.98551 0.46308 2.16868 0.16780 57833.093103 0.000503 0.20363 0.01681 0.98276 0 30.41863 1.00992 10.98280 0.36461 6.19407 0.46805 2.23732 0.16902 57833.094098 0.000492 0.20222 0.01610 0.98824 0 32.10802 1.04995 11.57467 0.37847 6.49277 0.47136 2.34186 0.17001 57833.095137 0.000547 0.18103 0.01461 0.99471 0 31.48743 0.98544 11.40108 0.35685 5.70006 0.42391 2.06490 0.15351 57833.096205 0.000521 0.18433 0.01451 0.98889 0 33.17010 1.04555 12.03589 0.37938 6.11411 0.44092 2.22046 0.16014 57833.097669 0.000943 0.19638 0.01169 0.98160 0 31.65629 0.76296 11.38678 0.27444 6.21670 0.33844 2.23602 0.12168
