/* ** ** 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 57387.764827 0.000122 0.19104 0.01493 1.00000 0 54.47030 1.70645 49.57808 1.55318 10.40575 0.74491 9.47137 0.67801 57387.765478 0.000530 0.22728 0.00809 1.00000 0 52.96213 0.81398 47.83497 0.73516 12.03730 0.38666 10.87027 0.34917 57387.766126 0.000119 0.18918 0.01469 1.00000 0 57.41887 1.79884 52.05698 1.63083 10.86228 0.77165 9.84897 0.69968 57387.766798 0.000553 0.21317 0.00763 1.00000 0 54.58102 0.81409 48.48105 0.72305 11.63521 0.37844 10.33986 0.33623 57387.767903 0.000553 0.20600 0.00737 1.00000 0 56.45548 0.82675 50.13957 0.73425 11.62999 0.37969 10.33079 0.33723 57387.768977 0.000521 0.22245 0.00805 0.99444 0 54.61950 0.83252 49.17417 0.74946 12.15019 0.39887 10.94018 0.35915 57387.769659 0.000162 0.19717 0.01328 1.00000 0 55.61992 1.51364 49.69258 1.35222 10.96663 0.67545 9.79142 0.60304 57387.770212 0.000391 0.19420 0.00836 1.00000 0 56.80254 0.98624 50.77196 0.88146 11.03126 0.43459 9.85947 0.38847 57387.771126 0.000524 0.22190 0.00812 1.00000 0 54.33245 0.83198 48.38751 0.74087 12.05642 0.40072 10.74003 0.35694 57387.772188 0.000538 0.21643 0.00771 1.00000 0 55.43445 0.83008 49.29644 0.73814 11.99744 0.38779 10.67021 0.34491 57387.773253 0.000527 0.21709 0.00779 1.00000 0 55.64254 0.83953 49.90964 0.75294 12.07955 0.39300 10.84017 0.35268 57387.774735 0.000955 0.21951 0.00580 1.00000 0 55.73867 0.62142 50.07438 0.55824 12.23496 0.29304 10.99014 0.26322
