/* ** ** 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 55278.018838 0.000347 0.26044 0.02146 0.99167 0 22.30044 0.82731 12.57818 0.46663 5.80795 0.42741 3.27500 0.24102 55278.019591 0.000405 0.21424 0.01725 0.98571 0 23.53922 0.78884 13.31832 0.44632 5.04305 0.36917 2.85312 0.20885 55278.020384 0.000388 0.23239 0.01879 0.97761 0 22.79703 0.78730 12.86061 0.44415 5.29789 0.38731 2.98892 0.21850 55278.021145 0.000373 0.23674 0.01892 0.99225 0 23.19154 0.82204 13.10371 0.46447 5.49048 0.39339 3.10171 0.22225 55278.021929 0.000411 0.22333 0.01845 0.97183 0 21.97675 0.75769 12.47427 0.43007 4.90812 0.36854 2.78444 0.20909 55278.022667 0.000327 0.24976 0.02064 1.00000 0 24.25685 0.88801 13.74011 0.50299 6.05828 0.44885 3.43275 0.25433 55278.023384 0.000391 0.22522 0.01844 0.99259 0 22.69170 0.78995 12.83918 0.44690 5.11072 0.37871 2.89478 0.21447 55278.024200 0.000425 0.22311 0.01813 0.97959 0 21.42590 0.73871 12.13432 0.41835 4.78032 0.35184 2.70642 0.19918 55278.025002 0.000376 0.23609 0.01857 1.00000 0 23.26253 0.81692 13.18570 0.46305 5.49214 0.38643 3.11287 0.21902 55278.025774 0.000396 0.21741 0.01743 0.99270 0 23.49969 0.79772 13.29983 0.45148 5.10913 0.37102 2.89244 0.21004 55278.026567 0.000396 0.21678 0.01723 1.00000 0 23.62857 0.79842 13.37084 0.45180 5.12232 0.36858 2.89926 0.20859 55278.027363 0.000399 0.21519 0.01736 1.00000 0 23.58067 0.79365 13.32911 0.44859 5.07424 0.37191 2.86894 0.21027 55278.028176 0.000414 0.21417 0.01712 0.97902 0 23.12297 0.77237 13.11751 0.43816 4.95232 0.35961 2.80980 0.20404 55278.029206 0.000616 0.23992 0.01500 0.99531 0 23.60010 0.64122 13.32367 0.36198 5.66218 0.31879 3.19641 0.17994
