/* ** ** 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 58820.194182 0.000399 0.12220 0.00945 0.99275 0 25.30217 0.63674 23.36744 0.58804 3.09188 0.22606 2.85825 0.20892 58820.194917 0.000336 0.15257 0.01157 0.98276 0 24.94486 0.69356 23.15068 0.64368 3.80592 0.26845 3.53219 0.24914 58820.195640 0.000388 0.12748 0.00961 0.98507 0 25.78593 0.65340 23.81857 0.60355 3.28711 0.23338 3.03676 0.21561 58820.196393 0.000359 0.14222 0.01079 1.00000 0 24.87403 0.66801 22.97289 0.61695 3.53767 0.25090 3.26649 0.23168 58820.197136 0.000385 0.13026 0.01006 1.00000 0 24.78006 0.65054 22.68036 0.59546 3.22779 0.23436 2.95787 0.21476 58820.197874 0.000353 0.14455 0.01110 1.00000 0 24.51772 0.67556 22.52364 0.62068 3.54392 0.25400 3.25436 0.23318 58820.198629 0.000402 0.11828 0.00908 0.99281 0 26.07366 0.64931 24.09224 0.59996 3.08409 0.22393 2.85070 0.20698 58820.199405 0.000373 0.13206 0.01036 0.99225 0 25.22340 0.66564 23.08739 0.60917 3.33095 0.24609 3.04647 0.22505 58820.200114 0.000336 0.15788 0.01210 0.99138 0 23.67922 0.67183 21.96735 0.62326 3.73839 0.26609 3.46826 0.24687 58820.200797 0.000347 0.14160 0.01104 0.99167 0 25.03769 0.68020 23.23853 0.63132 3.54535 0.25914 3.29058 0.24052 58820.201601 0.000457 0.13693 0.00936 0.99436 0 25.13766 0.60057 23.01557 0.54992 3.44215 0.22045 3.15191 0.20187
