/* ** ** 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 57459.903016 0.000518 0.08299 0.01285 0.98883 0 7.44537 0.31065 6.53342 0.27259 0.61786 0.09215 0.54240 0.08089 57459.903838 0.000304 0.06592 0.01571 0.96190 0 6.71657 0.38912 5.84366 0.33855 0.44276 0.10232 0.38640 0.08930 57459.904689 0.000547 0.08850 0.01323 0.97884 0 6.97706 0.29607 6.04933 0.25670 0.61746 0.08849 0.53582 0.07678 57459.905739 0.000503 0.09056 0.01391 0.99425 0 7.22188 0.31661 6.20440 0.27199 0.65399 0.09626 0.56096 0.08254 57459.906810 0.000567 0.08070 0.01203 0.98980 0 7.34413 0.29936 6.35254 0.25890 0.59270 0.08495 0.51096 0.07322 57459.908031 0.000654 0.06700 0.00991 0.97345 0 7.79656 0.28558 6.72024 0.24614 0.52237 0.07487 0.45057 0.06456 57459.909226 0.000541 0.08629 0.01288 0.97326 0 7.28217 0.30505 6.31259 0.26441 0.62838 0.09003 0.54465 0.07804 57459.910253 0.000486 0.09308 0.01395 0.99405 0 7.35474 0.32236 6.38759 0.27991 0.68457 0.09813 0.59357 0.08505 57459.911251 0.000512 0.08750 0.01265 0.97740 0 7.98138 0.32732 6.87825 0.28208 0.69838 0.09686 0.60216 0.08350 57459.912296 0.000532 0.08147 0.01245 0.97826 0 7.60371 0.31348 6.61200 0.27260 0.61947 0.09116 0.53914 0.07933 57459.913691 0.000862 0.08809 0.01021 0.97651 0 7.24955 0.23984 6.33446 0.20957 0.63860 0.07096 0.55763 0.06196
