/* ** ** 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 57125.744368 0.000530 0.23771 0.00862 1.00000 0 51.48487 0.81100 45.21646 0.71216 12.23847 0.39956 10.73880 0.35067 57125.745438 0.000541 0.23871 0.00873 1.00000 0 50.09925 0.79706 43.81384 0.69704 11.95903 0.39367 10.46078 0.34430 57125.746098 0.000119 0.22077 0.01771 1.00000 0 49.57962 1.71178 43.82145 1.51297 10.94560 0.79252 9.67435 0.70048 57125.746758 0.000541 0.24362 0.00884 1.00000 0 48.94887 0.78197 43.27008 0.69125 11.92476 0.38878 10.54123 0.34367 57125.747854 0.000556 0.23161 0.00834 1.00000 0 50.36626 0.78652 44.35022 0.69257 11.66547 0.37870 10.27721 0.33366 57125.748945 0.000535 0.23670 0.00859 1.00000 0 50.97780 0.80504 44.89438 0.70896 12.06650 0.39406 10.62270 0.34688 57125.750001 0.000521 0.24356 0.00887 1.00000 0 50.90482 0.81470 44.96208 0.71959 12.39844 0.40570 10.95110 0.35834 57125.750652 0.000130 0.22224 0.01700 1.00000 0 50.96944 1.65996 43.93596 1.43081 11.32723 0.78422 9.77142 0.67630 57125.751289 0.000506 0.25002 0.00906 0.99429 0 52.01469 0.84000 45.40789 0.73332 13.00473 0.42206 11.35189 0.36836 57125.752614 0.000819 0.23385 0.00701 1.00000 0 49.42834 0.64024 43.25921 0.56032 11.55896 0.31251 10.11896 0.27356
