/* ** ** 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 59142.211958 0.000353 0.32221 0.01192 1.00000 0 54.18966 0.99014 50.49209 0.92255 17.46068 0.56172 16.27134 0.52348 59142.212664 0.000353 0.31278 0.01155 1.00000 0 55.85904 1.00427 51.75816 0.93052 17.47143 0.56354 16.18923 0.52219 59142.213367 0.000350 0.31839 0.01172 1.00000 0 55.14541 1.00329 51.55984 0.93806 17.55759 0.56165 16.41599 0.52513 59142.214055 0.000339 0.33411 0.01243 1.00000 0 54.14883 1.00748 50.62810 0.94198 18.09165 0.58294 16.91532 0.54504 59142.214741 0.000347 0.32644 0.01202 1.00000 0 54.45439 0.99639 50.91415 0.93162 17.77632 0.56798 16.62064 0.53105 59142.215459 0.000370 0.31702 0.01167 1.00000 0 52.47722 0.94721 49.06557 0.88563 16.63610 0.53392 15.55456 0.49921 59142.216182 0.000353 0.32131 0.01183 1.00000 0 54.42890 0.98952 50.89024 0.92519 17.48832 0.56022 16.35133 0.52380 59142.216874 0.000339 0.32793 0.01215 1.00000 0 55.26956 1.02103 51.67651 0.95466 18.12454 0.58189 16.94627 0.54406 59142.217571 0.000359 0.30670 0.01119 1.00000 0 56.25939 0.99688 52.60148 0.93207 17.25485 0.55047 16.13295 0.51468 59142.218283 0.000353 0.31426 0.01150 1.00000 0 55.62881 0.99907 52.01183 0.93411 17.48165 0.55712 16.34500 0.52089 59142.218986 0.000350 0.32200 0.01180 1.00000 0 55.30362 1.00324 51.44466 0.93325 17.80790 0.56704 16.56499 0.52748 59142.219689 0.000353 0.31763 0.01170 1.00000 0 55.01157 0.99415 51.43447 0.92951 17.47317 0.56098 16.33702 0.52450 59142.220398 0.000356 0.33052 0.01220 1.00000 0 52.47749 0.96494 49.06679 0.90223 17.34464 0.55514 16.21735 0.51906 59142.221469 0.000715 0.30593 0.00797 1.00000 0 55.79880 0.70078 52.17121 0.65522 17.07047 0.38991 15.96068 0.36456
