/* ** ** 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 58153.252649 0.000385 0.27436 0.01001 1.00000 0 60.90559 1.03385 54.29450 0.92154 16.70999 0.53978 14.88216 0.48058 58153.253421 0.000388 0.26077 0.00952 1.00000 0 63.73308 1.05079 56.83223 0.93708 16.61950 0.54167 14.81613 0.48292 58153.254182 0.000373 0.27400 0.00992 1.00000 0 62.97648 1.06400 56.36811 0.95235 17.25526 0.55229 15.44447 0.49433 58153.254923 0.000367 0.26516 0.00971 1.00000 0 65.80053 1.09413 58.61405 0.97463 17.44748 0.56941 15.54597 0.50728 58153.255678 0.000388 0.26383 0.00972 1.00000 0 62.36087 1.04181 55.50677 0.92728 16.45256 0.54046 14.64423 0.48112 58153.256457 0.000391 0.26470 0.00970 1.00000 0 61.89166 1.03625 55.16748 0.92369 16.38257 0.53404 14.60244 0.47601 58153.257244 0.000396 0.26601 0.00971 1.00000 0 60.77821 1.01234 54.33377 0.90500 16.16752 0.52484 14.45504 0.46923 58153.258031 0.000391 0.26452 0.00962 1.00000 0 62.99989 1.05125 55.59359 0.92758 16.66502 0.53840 14.69881 0.47491 58153.258783 0.000362 0.28809 0.01062 1.00000 0 61.22813 1.06853 54.80187 0.95639 17.63941 0.57261 15.78660 0.51246 58153.259524 0.000379 0.26666 0.00971 1.00000 0 63.26020 1.05618 56.57951 0.94464 16.86882 0.54615 15.08646 0.48845 58153.260288 0.000385 0.26508 0.00976 1.00000 0 63.05794 1.05359 56.01840 0.93597 16.71552 0.54817 14.85227 0.48713 58153.261043 0.000370 0.28038 0.01028 1.00000 0 61.89901 1.07041 55.22718 0.95506 17.35526 0.56103 15.48700 0.50064 58153.261769 0.000356 0.28822 0.01069 1.00000 0 62.13939 1.08543 55.54423 0.97023 17.90997 0.58626 16.01085 0.52409 58153.262493 0.000367 0.28571 0.01050 0.99213 0 61.95510 1.07021 54.86203 0.94753 17.70124 0.57429 15.67721 0.50864 58153.263225 0.000365 0.28608 0.01051 1.00000 0 61.42067 1.06831 54.88442 0.95464 17.57152 0.56861 15.70103 0.50809 58153.264087 0.000498 0.27489 0.00875 1.00000 0 62.55043 0.92598 55.70215 0.82450 17.19477 0.48434 15.31072 0.43121
