/* ** ** 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 55566.370277 0.000631 0.10537 0.00824 0.98165 0 19.47750 0.45715 17.15713 0.40270 2.05225 0.15302 1.80467 0.13453 55566.371515 0.000608 0.11469 0.00861 0.96667 0 19.40704 0.46411 17.13126 0.40968 2.22580 0.15842 1.96482 0.13985 55566.372754 0.000631 0.10447 0.00797 0.99541 0 19.65762 0.45920 17.35515 0.40542 2.05368 0.14909 1.81305 0.13162 55566.373983 0.000599 0.11227 0.00853 0.98551 0 19.55312 0.46997 17.25715 0.41479 2.19521 0.15831 1.93746 0.13973 55566.375202 0.000619 0.10961 0.00822 0.99533 0 19.36190 0.45963 17.08413 0.40556 2.12225 0.15105 1.87257 0.13328 55566.376362 0.000541 0.12362 0.00956 0.98930 0 19.39507 0.49163 17.12468 0.43408 2.39755 0.17520 2.11689 0.15470 55566.377699 0.000796 0.11055 0.00731 0.99862 0 19.38264 0.40653 17.10839 0.35883 2.14278 0.13439 1.89152 0.11863 55566.441839 0.000666 0.10654 0.00825 1.00000 0 19.86134 0.47205 15.94046 0.37869 2.11610 0.15602 1.69364 0.12475 55566.443040 0.000535 0.12368 0.00963 0.98378 0 20.88159 0.52878 17.30334 0.43816 2.58266 0.19024 2.14031 0.15766 55566.444206 0.000631 0.11238 0.00855 0.98165 0 19.90141 0.47996 16.42752 0.39619 2.23657 0.16141 1.84627 0.13324 55566.445430 0.000593 0.12194 0.00926 0.99512 0 19.30217 0.48537 15.95646 0.40124 2.35369 0.16870 1.94587 0.13947 55566.446619 0.000596 0.11340 0.00852 0.99029 0 20.82588 0.50029 17.24169 0.41420 2.36161 0.16812 1.95496 0.13918 55566.447898 0.000683 0.09945 0.00757 1.00000 0 20.20706 0.46109 16.75916 0.38241 2.00950 0.14601 1.66630 0.12107 55566.449270 0.000689 0.13052 0.00889 0.99160 0 19.42828 0.45148 16.07862 0.37364 2.53570 0.16245 2.09797 0.13441
