/* ** ** 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 59934.264096 0.000503 0.10716 0.00821 0.98851 0 24.35205 0.57343 21.40439 0.50398 2.60946 0.19020 2.28831 0.16681 59934.265089 0.000489 0.10951 0.00820 0.99408 0 24.74307 0.58537 21.78915 0.51549 2.70958 0.19238 2.38604 0.16941 59934.266070 0.000492 0.10356 0.00794 1.00000 0 25.57561 0.59755 22.25624 0.51999 2.64854 0.19355 2.30345 0.16836 59934.267106 0.000544 0.10043 0.00756 0.98936 0 24.28673 0.55235 21.37736 0.48617 2.43921 0.17504 2.14637 0.15401 59934.268165 0.000515 0.10285 0.00779 0.98876 0 24.92998 0.57598 21.82529 0.50423 2.56393 0.18496 2.24556 0.16196 59934.269154 0.000475 0.10959 0.00829 0.99390 0 25.95629 0.61313 22.46637 0.53066 2.84448 0.20440 2.46267 0.17695 59934.270147 0.000518 0.10074 0.00767 0.98324 0 25.30715 0.57908 22.17582 0.50741 2.54933 0.18513 2.23524 0.16229 59934.271168 0.000503 0.10543 0.00795 0.98851 0 24.93689 0.58314 21.89142 0.51194 2.62906 0.18837 2.30834 0.16539 59934.272247 0.000576 0.08910 0.00675 0.99497 0 25.29426 0.54570 22.30058 0.48112 2.25362 0.16362 1.98688 0.14426 59934.273555 0.000732 0.10677 0.00672 0.99209 0 24.87043 0.48064 21.81125 0.42149 2.65530 0.15911 2.32855 0.13952
