/* ** ** 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 58880.173348 0.000289 0.13362 0.01035 0.98000 0 33.58218 0.87562 30.05803 0.78369 4.48722 0.32734 4.01509 0.29284 58880.173871 0.000234 0.15870 0.01256 1.00000 0 33.72629 0.98064 30.30839 0.88126 5.35223 0.39408 4.81034 0.35416 58880.174360 0.000255 0.14601 0.01133 1.00000 0 34.58236 0.95953 30.78256 0.85402 5.04951 0.36595 4.49224 0.32544 58880.174864 0.000249 0.14849 0.01176 0.98837 0 34.24910 0.95367 30.72544 0.85555 5.08557 0.37697 4.56235 0.33818 58880.175379 0.000266 0.13506 0.01071 0.98913 0 35.24976 0.94474 31.40716 0.84171 4.76071 0.35535 4.24134 0.31653 58880.175897 0.000252 0.15609 0.01219 1.00000 0 32.26382 0.92591 28.96449 0.83123 5.03595 0.36579 4.52085 0.32838 58880.176380 0.000231 0.15604 0.01212 1.00000 0 35.26237 1.01754 31.65541 0.91346 5.50226 0.39698 4.93940 0.35637 58880.176889 0.000278 0.13629 0.01082 1.00000 0 32.85695 0.89110 29.49952 0.80004 4.47804 0.33420 4.02043 0.30005 58880.177416 0.000249 0.14623 0.01115 1.00000 0 35.32806 0.96749 31.71338 0.86849 5.16610 0.36775 4.63754 0.33013 58880.178050 0.000385 0.16464 0.01009 0.98274 0 33.02664 0.75995 29.64306 0.68209 5.43736 0.30889 4.88038 0.27725
