/* ** ** 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 59752.176390 0.000584 0.10859 0.00810 0.99010 0 20.46893 0.47867 18.56613 0.43412 2.22270 0.15743 2.01418 0.14266 59752.177559 0.000584 0.10771 0.00826 0.98020 0 20.26867 0.47916 18.44825 0.43608 2.18312 0.15921 1.98726 0.14494 59752.178705 0.000561 0.11097 0.00860 0.98454 0 20.12370 0.48689 18.38340 0.44479 2.23308 0.16441 2.03998 0.15019 59752.179828 0.000561 0.11059 0.00830 0.98969 0 20.56937 0.49078 18.78310 0.44816 2.27468 0.16193 2.07723 0.14787 59752.180971 0.000582 0.10718 0.00814 0.98507 0 20.39402 0.48364 18.62050 0.44158 2.18577 0.15770 1.99572 0.14399 59752.182154 0.000602 0.10435 0.00781 0.98077 0 20.52330 0.47130 18.73547 0.43025 2.14159 0.15245 1.95504 0.13917 59752.183384 0.000628 0.09876 0.00750 0.99078 0 20.44457 0.46369 18.61474 0.42219 2.01916 0.14627 1.83868 0.13321 59752.184651 0.000639 0.09411 0.00714 0.98643 0 21.06890 0.46424 19.17941 0.42260 1.98273 0.14404 1.80419 0.13105 59752.186037 0.000747 0.11430 0.00745 0.98837 0 20.26438 0.42482 18.51218 0.38809 2.31624 0.14297 2.11591 0.13060
