/* ** ** 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 55322.866161 0.000122 0.30507 0.02446 1.00000 0 34.48629 1.34662 31.89744 1.24553 10.52062 0.73659 9.73048 0.68127 55322.866815 0.000532 0.31821 0.01175 1.00000 0 36.68296 0.66394 33.88998 0.61339 11.67279 0.37579 10.78385 0.34717 55322.867665 0.000318 0.29167 0.01435 1.00000 0 36.69345 0.85992 33.91462 0.79480 10.70251 0.46291 9.89200 0.42785 55322.868143 0.000159 0.28368 0.01990 1.00000 0 37.39059 1.23273 34.55897 1.13937 10.60702 0.65697 9.80374 0.60722 55322.868866 0.000564 0.30932 0.01135 1.00000 0 35.67931 0.63469 32.97680 0.58661 11.03636 0.35409 10.20042 0.32727 55322.869700 0.000269 0.30162 0.01639 0.98925 0 35.26999 0.92085 32.59860 0.85111 10.63818 0.50707 9.83243 0.46866 55322.870533 0.000564 0.30041 0.01105 0.99487 0 36.62111 0.64462 33.84740 0.59580 11.00125 0.35549 10.16801 0.32857 55322.871245 0.000148 0.29431 0.02157 1.00000 0 35.97894 1.25436 33.25383 1.15935 10.58910 0.68254 9.78704 0.63084 55322.871514 0.000122 0.29574 0.02384 1.00000 0 35.49115 1.38015 32.80322 1.27563 10.49605 0.74125 9.70114 0.68511 55322.871922 0.000286 0.28834 0.01514 1.00000 0 36.71310 0.90506 33.93248 0.83651 10.58573 0.49078 9.78398 0.45360 55322.872330 0.000122 0.30290 0.02483 0.97619 0 34.89939 1.36728 32.25634 1.26373 10.57108 0.76108 9.77050 0.70344 55322.872590 0.000139 0.29308 0.02204 1.00000 0 36.17146 1.29994 33.43210 1.20149 10.60123 0.70044 9.79837 0.64739 55322.872851 0.000122 0.28334 0.02307 1.00000 0 36.16849 1.39161 33.42902 1.28620 10.24802 0.73521 9.47182 0.67953 55322.873455 0.000483 0.28754 0.01163 1.00000 0 36.79793 0.69800 34.01076 0.64513 10.58096 0.37781 9.77953 0.34920 55322.874485 0.000547 0.31719 0.01167 1.00000 0 35.84893 0.64786 33.13332 0.59878 11.37093 0.36456 10.50956 0.33694 55322.875162 0.000130 0.26821 0.02172 1.00000 0 35.66154 1.33872 32.96048 1.23732 9.56482 0.68620 8.84036 0.63422 55322.875863 0.000570 0.30297 0.01108 1.00000 0 35.99348 0.63514 33.26733 0.58703 10.90481 0.34918 10.07887 0.32273 55322.877104 0.000671 0.30329 0.01012 1.00000 0 36.79453 0.59118 34.00768 0.54640 11.15949 0.32643 10.31426 0.30170
