/* ** ** 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 57925.085441 0.000341 0.18441 0.01432 1.00000 0 20.40866 0.62656 18.34014 0.56299 3.76359 0.26846 3.37335 0.24061 57925.086121 0.000339 0.19626 0.01520 0.99145 0 19.71280 0.61999 17.76956 0.55888 3.86879 0.27387 3.48332 0.24658 57925.086778 0.000318 0.20504 0.01607 0.99091 0 19.71540 0.63548 17.86706 0.57590 4.04253 0.28884 3.65828 0.26140 57925.087458 0.000362 0.18118 0.01417 1.00000 0 19.25595 0.59090 17.44709 0.53540 3.48871 0.25103 3.16355 0.22761 57925.088190 0.000370 0.17136 0.01328 0.98438 0 20.37382 0.60082 18.37507 0.54185 3.49120 0.25013 3.14881 0.22557 57925.088928 0.000367 0.17608 0.01381 1.00000 0 19.38464 0.58535 17.65679 0.53317 3.41316 0.24708 3.10894 0.22505 57925.089712 0.000417 0.15503 0.01193 0.98611 0 19.95699 0.56221 18.02587 0.50775 3.09402 0.22162 2.79401 0.20015 57925.090493 0.000365 0.18085 0.01404 0.99206 0 19.77341 0.60024 17.64894 0.53573 3.57607 0.25549 3.19002 0.22794 57925.091182 0.000324 0.20464 0.01606 0.97321 0 19.67329 0.63001 17.81037 0.57035 4.02591 0.28839 3.63990 0.26075 57925.091876 0.000370 0.17886 0.01377 1.00000 0 19.62572 0.59274 17.54452 0.52988 3.51023 0.24868 3.13566 0.22213 57925.092597 0.000350 0.17797 0.01390 1.00000 0 20.46015 0.62114 18.38431 0.55805 3.64123 0.26200 3.26813 0.23514 57925.093334 0.000388 0.17291 0.01335 0.97761 0 19.55870 0.57813 17.56252 0.51906 3.38181 0.24122 3.03859 0.21673 57925.094110 0.000388 0.16891 0.01310 0.99254 0 19.62353 0.57621 17.69674 0.51960 3.31461 0.23791 2.98832 0.21445 57925.094859 0.000362 0.17459 0.01377 0.99200 0 20.10142 0.60582 18.09895 0.54540 3.50953 0.25584 3.15747 0.23017 57925.095591 0.000370 0.17092 0.01339 1.00000 0 20.12249 0.60146 18.04591 0.53928 3.43937 0.24902 3.08465 0.22329 57925.096569 0.000608 0.16631 0.01034 0.99048 0 20.26607 0.47064 18.15615 0.42162 3.37037 0.19429 3.01635 0.17393
