/* ** ** 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 55287.002777 0.000436 0.35912 0.04123 0.99892 1 19.90463 1.18966 3.92811 0.23478 7.14808 0.70059 1.41029 0.13822 55287.004156 0.000179 0.26664 0.02137 1.00000 0 26.21201 0.96686 24.12777 0.88998 6.98910 0.49743 6.43336 0.45788 55287.004541 0.000205 0.23044 0.01867 1.00000 0 26.38767 0.91659 24.06050 0.83568 6.08089 0.44495 5.54765 0.40580 55287.004917 0.000171 0.27235 0.02232 1.00000 0 26.75006 1.01257 24.62446 0.93211 7.28536 0.52945 6.70647 0.48738 55287.005290 0.000203 0.23018 0.01816 1.00000 0 27.02837 0.93154 24.87969 0.85748 6.22130 0.44167 5.72674 0.40656 55287.005669 0.000177 0.28271 0.02294 1.00000 0 25.27925 0.96805 23.26942 0.89108 7.14658 0.51135 6.57839 0.47070 55287.006028 0.000182 0.26258 0.02129 1.00000 0 26.10139 0.96373 24.02753 0.88716 6.85378 0.49486 6.30921 0.45554 55287.006407 0.000197 0.23418 0.01922 1.00000 0 26.47379 0.93696 24.36961 0.86249 6.19976 0.45895 5.70704 0.42247 55287.006780 0.000177 0.28846 0.02343 0.98361 0 25.30306 0.97719 23.04595 0.89009 7.29894 0.52157 6.65122 0.47526 55287.007168 0.000211 0.22150 0.01774 0.98630 0 26.80309 0.90614 24.67206 0.83409 5.93692 0.43091 5.46491 0.39665 55287.007547 0.000168 0.30523 0.02457 1.00000 0 24.95622 0.98376 22.97205 0.90554 7.61730 0.53463 7.01167 0.49212 55287.007892 0.000177 0.25718 0.02119 1.00000 0 26.99793 1.00418 24.85237 0.92438 6.94319 0.51061 6.39142 0.47003 55287.008245 0.000177 0.26770 0.02158 1.00000 0 26.54882 0.99155 24.43803 0.91272 7.10723 0.50785 6.54219 0.46747 55287.008612 0.000191 0.26046 0.02080 1.00000 0 25.33248 0.92716 23.31923 0.85348 6.59819 0.46842 6.07381 0.43120 55287.008962 0.000159 0.29830 0.02480 1.00000 0 25.93546 1.02913 23.87349 0.94731 7.73644 0.56522 7.12137 0.52028 55287.009324 0.000203 0.24559 0.01960 0.98571 0 25.58325 0.90860 23.55008 0.83639 6.28301 0.44895 5.78367 0.41327 55287.009700 0.000174 0.28654 0.02311 1.00000 0 25.45634 0.98209 23.43308 0.90403 7.29434 0.51655 6.71458 0.47549 55287.010067 0.000194 0.24961 0.02057 1.00000 0 25.33753 0.92811 23.32465 0.85438 6.32456 0.46691 5.82212 0.42982 55287.010438 0.000177 0.26760 0.02215 1.00000 0 25.94537 0.98498 23.88409 0.90673 6.94302 0.51059 6.39142 0.47003 55287.010860 0.000246 0.25397 0.01786 0.99763 0 26.31384 0.83484 24.22378 0.76853 6.68284 0.41951 6.15204 0.38619
