/* ** ** 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 59291.918079 0.000616 0.15227 0.01168 0.98592 0 17.43246 0.48587 12.71306 0.35290 2.65443 0.18971 1.89920 0.13519 59291.919335 0.000639 0.15957 0.01264 0.98190 0 17.08947 0.49794 11.23061 0.32697 2.72691 0.20080 1.79565 0.13219 59291.920701 0.000726 0.13095 0.01006 0.99203 0 18.29849 0.48243 12.09635 0.31885 2.39624 0.17294 1.58699 0.11449 59291.922078 0.000651 0.15250 0.01203 0.98222 0 17.32764 0.49081 11.55734 0.32734 2.64249 0.19455 1.76315 0.12980 59291.923386 0.000657 0.14713 0.01165 0.98238 0 17.73309 0.49419 11.81850 0.32937 2.60915 0.19339 1.73911 0.12890 59291.924856 0.000813 0.14308 0.01015 0.99172 0 17.70802 0.44168 11.82564 0.29495 2.53362 0.16820 1.69239 0.11234
