/* ** ** 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 54506.150418 0.000130 0.17460 0.01369 1.00000 0 61.67395 1.84317 51.12220 1.52733 10.76849 0.78060 8.93155 0.64725 54506.151087 0.000538 0.21246 0.00758 0.99462 0 59.38059 0.87984 50.38844 0.74660 12.61583 0.40926 10.69846 0.34710 54506.151781 0.000156 0.19549 0.01344 1.00000 0 58.88952 1.64236 50.04406 1.39569 11.51242 0.72355 9.78018 0.61452 54506.152059 0.000122 0.19706 0.01526 1.00000 0 56.92948 1.83805 48.88634 1.57841 11.21857 0.78934 9.63509 0.67792 54506.152698 0.000518 0.21505 0.00768 1.00000 0 60.66761 0.90989 51.35381 0.77004 13.04681 0.42289 11.03981 0.35783 54506.153746 0.000530 0.21546 0.00779 0.99454 0 59.74685 0.89756 49.97106 0.75067 12.87328 0.42354 10.76153 0.35413 54506.154814 0.000538 0.20641 0.00739 1.00000 0 60.87386 0.89464 51.31566 0.75414 12.56512 0.40998 10.59875 0.34578 54506.155904 0.000553 0.20183 0.00709 0.98953 0 61.60376 0.88738 52.08062 0.75012 12.43337 0.39835 10.51178 0.33680 54506.156984 0.000527 0.20684 0.00748 1.00000 0 61.71594 0.91433 52.01160 0.77050 12.76528 0.42100 10.75648 0.35466 54506.157632 0.000122 0.19531 0.01572 1.00000 0 57.83662 1.86289 48.14117 1.55036 11.29598 0.83327 9.40457 0.69369 54506.158051 0.000298 0.19249 0.00960 1.00000 0 61.17250 1.22073 50.82814 1.01426 11.77486 0.53812 9.77924 0.44688 54506.158882 0.000532 0.21739 0.00775 1.00000 0 58.40957 0.88397 49.50735 0.74920 12.69771 0.40975 10.76068 0.34722 54506.159958 0.000544 0.20657 0.00744 1.00000 0 58.91542 0.87189 50.37403 0.74546 12.17039 0.39987 10.41230 0.34214 54506.161038 0.000535 0.20972 0.00748 1.00000 0 59.99586 0.88580 50.91679 0.75166 12.58206 0.40861 10.67680 0.34676 54506.162123 0.000550 0.20841 0.00750 1.00000 0 58.07295 0.85677 49.55830 0.73114 12.10304 0.39712 10.33433 0.33903 54506.163205 0.000532 0.20358 0.00739 0.99457 0 59.00275 0.87871 50.69602 0.75499 12.01155 0.39779 10.32184 0.34185
