/* ** ** 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 57089.011454 0.000402 0.24957 0.01086 1.00000 0 48.12109 0.93317 39.36327 0.76316 12.00979 0.46801 9.81508 0.38242 57089.011977 0.000122 0.22146 0.01765 1.00000 0 50.61941 1.72138 42.93113 1.45998 11.21014 0.80802 9.50685 0.68527 57089.012649 0.000550 0.25645 0.00927 1.00000 0 47.44280 0.77376 40.58730 0.66195 12.16689 0.39242 10.40857 0.33571 57089.013395 0.000197 0.23235 0.01435 1.00000 0 49.49169 1.32761 42.28204 1.13421 11.49934 0.63968 9.82422 0.54650 57089.013714 0.000122 0.24283 0.01940 1.00000 0 45.74979 1.63113 39.11990 1.39475 11.10960 0.79420 9.49942 0.67910 57089.013954 0.000119 0.22900 0.01803 1.00000 0 50.42458 1.72353 43.13348 1.47432 11.54722 0.81924 9.87770 0.70079 57089.014651 0.000579 0.23359 0.00838 1.00000 0 49.59765 0.77287 42.38340 0.66045 11.58563 0.37441 9.90050 0.31995 57089.015785 0.000556 0.24186 0.00866 1.00000 0 50.29100 0.79580 42.83623 0.67782 12.16351 0.39048 10.36113 0.33259 57089.016862 0.000521 0.23826 0.00913 1.00000 0 47.97815 0.80144 41.00214 0.68491 11.43127 0.39433 9.76863 0.33697 57089.017507 0.000124 0.23111 0.01872 1.00000 0 46.30582 1.62945 39.59031 1.39313 10.70181 0.78070 9.14962 0.66746 57089.017764 0.000133 0.20242 0.01607 1.00000 0 50.42869 1.63494 43.12863 1.39827 10.20787 0.73986 8.73050 0.63276 57089.018456 0.000558 0.24751 0.00890 1.00000 0 48.55580 0.77827 41.48300 0.66490 12.01787 0.38689 10.26673 0.33052 57089.019556 0.000541 0.24847 0.00897 0.99465 0 50.01736 0.80232 42.75653 0.68585 12.42764 0.40171 10.62332 0.34339 57089.020230 0.000133 0.24206 0.01803 1.00000 0 47.85432 1.59336 40.85472 1.36030 11.58360 0.77169 9.88941 0.65883 57089.020594 0.000231 0.24542 0.01349 1.00000 0 50.63328 1.23519 43.31885 1.05676 12.42665 0.61185 10.63133 0.52346
