/* ** ** 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 57880.179899 0.000269 0.18584 0.01447 1.00000 0 25.78102 0.79706 23.10625 0.71440 4.79102 0.34237 4.29116 0.30662 57880.180472 0.000304 0.16327 0.01278 1.00000 0 25.61627 0.74629 23.08149 0.67245 4.18242 0.30393 3.76849 0.27385 57880.181048 0.000272 0.18989 0.01519 1.00000 0 24.52172 0.77793 22.07894 0.70043 4.65637 0.34188 4.19257 0.30783 57880.181621 0.000301 0.16630 0.01352 1.00000 0 24.57209 0.74253 22.12780 0.66867 4.08623 0.30853 3.67982 0.27784 57880.182171 0.000249 0.18734 0.01500 1.00000 0 26.87033 0.85030 24.19923 0.76577 5.03395 0.37018 4.53358 0.33339 57880.182671 0.000252 0.20590 0.01639 0.98851 0 24.67433 0.80528 22.22140 0.72522 5.08046 0.36873 4.57536 0.33207 57880.183235 0.000312 0.17049 0.01309 0.99074 0 24.52585 0.72686 22.08501 0.65452 4.18132 0.29610 3.76521 0.26663 57880.183834 0.000286 0.18455 0.01446 1.00000 0 24.14912 0.75042 21.74549 0.67573 4.45662 0.32052 4.01294 0.28861 57880.184419 0.000298 0.17030 0.01348 0.98058 0 25.30382 0.75374 22.78430 0.67869 4.30923 0.31604 3.88011 0.28457 57880.184992 0.000275 0.19200 0.01520 0.97895 0 24.47177 0.77285 22.03587 0.69592 4.69857 0.34102 4.23098 0.30708 57880.185582 0.000315 0.16674 0.01293 1.00000 0 24.39995 0.72061 21.96944 0.64883 4.06843 0.29184 3.66316 0.26277 57880.186184 0.000286 0.18640 0.01459 0.97980 0 24.39959 0.75476 21.97247 0.67968 4.54814 0.32710 4.09568 0.29456 57880.186711 0.000240 0.20832 0.01633 1.00000 0 25.62129 0.84276 23.06863 0.75880 5.33740 0.37987 4.80567 0.34203 57880.187231 0.000281 0.18505 0.01477 0.98969 0 24.77641 0.76973 22.30933 0.69309 4.58479 0.33700 4.12824 0.30344 57880.187807 0.000295 0.17542 0.01346 1.00000 0 25.13287 0.75401 22.62893 0.67889 4.40876 0.31142 3.96942 0.28039 57880.188406 0.000304 0.15479 0.01259 1.00000 0 26.02393 0.75439 23.43617 0.67937 4.02829 0.30617 3.62767 0.27573 57880.188956 0.000246 0.21362 0.01666 0.98824 0 25.05619 0.82914 22.56292 0.74663 5.35254 0.37809 4.82001 0.34047 57880.189494 0.000292 0.17959 0.01415 0.98020 0 24.56729 0.75381 22.13053 0.67904 4.41208 0.32022 3.97456 0.28847 57880.190073 0.000286 0.18413 0.01446 0.97980 0 24.85054 0.76092 22.37920 0.68525 4.57567 0.33077 4.12060 0.29788 57880.190634 0.000275 0.18484 0.01466 0.97895 0 25.29951 0.78048 22.78551 0.70293 4.67648 0.34164 4.21166 0.30769 57880.191178 0.000269 0.19446 0.01566 0.98925 0 24.20922 0.77984 21.80531 0.70240 4.70761 0.34752 4.24016 0.31301 57880.191725 0.000278 0.18543 0.01449 1.00000 0 24.91088 0.77353 22.43002 0.69649 4.61921 0.33135 4.15921 0.29836 57880.192521 0.000518 0.18382 0.01023 1.00000 0 26.53615 0.58243 23.90490 0.52468 4.87776 0.24935 4.39413 0.22463
