/* ** ** 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 57108.045170 0.000547 0.22395 0.00798 1.00000 0 50.13322 0.76094 46.81749 0.71061 11.22747 0.36187 10.48191 0.33781 57108.046258 0.000541 0.22088 0.00781 1.00000 0 51.74469 0.77931 48.08622 0.72418 11.42944 0.36585 10.62448 0.34009 57108.047331 0.000532 0.22175 0.00792 1.00000 0 52.66358 0.79773 48.61060 0.73627 11.67789 0.37766 10.78164 0.34859 57108.048405 0.000541 0.21918 0.00792 0.99465 0 52.02112 0.78639 47.93031 0.72452 11.40201 0.37441 10.51206 0.34514 57108.049481 0.000535 0.22440 0.00800 1.00000 0 51.64931 0.78914 47.73152 0.72921 11.59026 0.37319 10.70000 0.34452 57108.050546 0.000530 0.21970 0.00784 1.00000 0 53.22464 0.80194 49.30293 0.74282 11.69351 0.37808 10.84055 0.35049 57108.051605 0.000530 0.21528 0.00762 1.00000 0 54.20407 0.80694 50.30752 0.74892 11.66911 0.37499 10.83020 0.34803 57108.052670 0.000535 0.21695 0.00777 1.00000 0 52.68601 0.79048 49.16988 0.73772 11.43003 0.37155 10.66465 0.34669 57108.053735 0.000530 0.22158 0.00787 1.00000 0 52.81894 0.79908 49.07987 0.74247 11.70345 0.37583 10.87168 0.34914 57108.055254 0.000990 0.21663 0.00572 0.99708 0 52.25848 0.57751 48.78929 0.53916 11.32081 0.27144 10.56980 0.25342
