/* ** ** 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 59305.002760 0.000436 0.15854 0.03111 0.99892 1 12.05303 0.89245 2.57874 0.19094 1.91087 0.34727 0.40926 0.07438 59305.004347 0.000631 0.11813 0.00912 0.99083 0 17.09934 0.42528 15.34700 0.38169 2.01998 0.14763 1.81297 0.13250 59305.005586 0.000608 0.11820 0.00907 0.99524 0 17.74312 0.44092 15.92481 0.39573 2.09730 0.15227 1.88237 0.13666 59305.006925 0.000732 0.12931 0.00878 0.98717 0 17.66962 0.40107 15.85884 0.35997 2.28490 0.14623 2.05075 0.13125 59305.062014 0.000538 0.14965 0.01161 0.97312 0 15.47562 0.42824 14.52790 0.40202 2.31597 0.16779 2.17414 0.15752 59305.063217 0.000666 0.13123 0.00960 0.97389 0 15.59888 0.38628 14.64361 0.36263 2.04698 0.14084 1.92162 0.13221
