/* ** ** 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 59699.044163 0.000327 0.09102 0.01393 0.97345 0 10.80948 0.46703 9.68027 0.41821 0.98384 0.14449 0.88338 0.12973 59699.045584 0.001094 0.10868 0.00824 0.98413 0 10.83830 0.25549 9.76863 0.23025 1.17796 0.08487 1.06096 0.07644 59699.046978 0.000301 0.10492 0.01564 0.99038 0 10.58686 0.48891 9.37545 0.43294 1.11077 0.15746 0.98225 0.13924 59699.047641 0.000362 0.10885 0.01486 1.00000 0 9.98708 0.42876 8.99942 0.38638 1.08706 0.14085 0.97768 0.12670 59699.048431 0.000428 0.07209 0.01069 0.95946 0 10.89935 0.41625 9.68804 0.36996 0.78572 0.11253 0.69837 0.10001 59699.049939 0.001079 0.09938 0.00798 0.97319 0 11.00622 0.26121 9.80391 0.23267 1.09379 0.08386 0.97416 0.07471 59699.051319 0.000301 0.10724 0.01616 0.99038 0 9.94642 0.46725 8.98624 0.42210 1.06667 0.15274 0.96280 0.13787 59699.052873 0.001247 0.11299 0.00803 0.97680 0 10.73674 0.24567 9.60074 0.21969 1.21320 0.08165 1.08503 0.07302
