/* ** ** 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 59946.250945 0.000177 0.15064 0.01157 1.00000 0 49.08974 1.36001 43.29465 1.19945 7.39507 0.52996 6.52142 0.46731 59946.251293 0.000171 0.15482 0.01170 1.00000 0 51.16057 1.42577 44.90611 1.25148 7.92091 0.55617 6.95348 0.48821 59946.251634 0.000171 0.15156 0.01170 1.00000 0 50.66667 1.42170 44.38063 1.24514 7.67900 0.55247 6.72188 0.48359 59946.251990 0.000185 0.13914 0.01064 1.00000 0 51.74427 1.39000 44.98894 1.20838 7.19956 0.51546 6.25934 0.44800 59946.252372 0.000197 0.13288 0.01016 1.00000 0 50.72248 1.33406 44.10882 1.16013 6.74016 0.48372 5.86168 0.42062 59946.252751 0.000182 0.13576 0.01036 1.00000 0 52.97667 1.40871 46.44615 1.23499 7.19211 0.51466 6.30189 0.45095 59946.253101 0.000168 0.15482 0.01197 1.00000 0 50.43248 1.42783 44.58818 1.26238 7.80797 0.56178 6.89948 0.49644 59946.253442 0.000174 0.15548 0.01196 0.98333 0 49.93312 1.39732 43.75814 1.22445 7.76356 0.55642 6.80314 0.48759 59946.253798 0.000182 0.14693 0.01107 1.00000 0 49.61806 1.35620 43.93273 1.20081 7.29037 0.51168 6.45518 0.45306 59946.254172 0.000191 0.13607 0.01032 0.98485 0 51.22184 1.34342 45.33932 1.18914 6.96998 0.49622 6.16963 0.43924 59946.254533 0.000171 0.16058 0.01225 1.00000 0 49.08386 1.40029 42.97805 1.22600 7.88213 0.55771 6.91226 0.48908 59946.254872 0.000168 0.14883 0.01134 1.00000 0 52.28228 1.44453 46.27881 1.27865 7.78132 0.55240 6.88708 0.48892 59946.255205 0.000165 0.15285 0.01180 1.00000 0 51.31170 1.44540 45.43027 1.27972 7.84296 0.56346 6.94392 0.49887 59946.255555 0.000185 0.13950 0.01071 0.98438 0 50.97735 1.36158 45.12511 1.20527 7.11151 0.51162 6.29510 0.45289 59946.255911 0.000171 0.14798 0.01129 1.00000 0 52.00815 1.43857 45.78201 1.26626 7.69602 0.54719 6.78370 0.48227 59946.256264 0.000182 0.13378 0.01015 1.00000 0 54.73758 1.43858 47.55745 1.24985 7.32278 0.52130 6.36549 0.45318 59946.256620 0.000174 0.14299 0.01097 1.00000 0 52.95924 1.43541 46.48904 1.25997 7.57286 0.54345 6.64324 0.47670 59946.256964 0.000171 0.14870 0.01134 1.00000 0 52.38475 1.45443 45.54642 1.26443 7.78961 0.55305 6.77035 0.48064 59946.257389 0.000255 0.14040 0.00933 0.96613 0 50.96690 1.17317 44.46115 1.02340 7.15585 0.44594 6.24768 0.38929
