/* ** ** 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 54906.581020 0.000298 0.15298 0.01181 0.99029 0 28.20519 0.78375 25.40430 0.70592 4.31490 0.31064 3.88653 0.27980 54906.581581 0.000263 0.18943 0.01487 1.00000 0 25.83275 0.80764 23.01928 0.71966 4.89357 0.35232 4.35634 0.31362 54906.582128 0.000284 0.17797 0.01368 0.97959 0 26.67123 0.79488 23.48535 0.69985 4.74658 0.33620 4.18147 0.29614 54906.582704 0.000292 0.15559 0.01203 1.00000 0 28.53238 0.80939 25.15981 0.71366 4.43947 0.31922 3.91754 0.28160 54906.583286 0.000289 0.16491 0.01279 1.00000 0 27.35841 0.79811 24.00245 0.70019 4.51171 0.32429 3.95672 0.28441 54906.583861 0.000286 0.16996 0.01312 1.00000 0 26.97433 0.79825 23.67260 0.70049 4.58466 0.32684 4.02191 0.28673 54906.584484 0.000336 0.15366 0.01178 0.99138 0 25.49349 0.71236 22.54007 0.62980 3.91726 0.27974 3.46890 0.24769 54906.585120 0.000301 0.15778 0.01217 0.99038 0 27.87253 0.79075 24.49521 0.69494 4.39780 0.31534 3.86092 0.27681 54906.585768 0.000347 0.13456 0.01042 0.99167 0 27.61685 0.72832 24.47817 0.64550 3.71613 0.27055 3.29349 0.23969 54906.586376 0.000260 0.17478 0.01373 1.00000 0 28.32306 0.85632 24.98601 0.75540 4.95026 0.35880 4.36860 0.31662 54906.586937 0.000301 0.15276 0.01179 1.00000 0 28.24421 0.79276 24.92537 0.69956 4.31450 0.31013 3.80454 0.27347 54906.587536 0.000298 0.16489 0.01294 1.00000 0 25.95348 0.76164 23.08300 0.67737 4.27937 0.31143 3.80510 0.27693 54906.588135 0.000301 0.15432 0.01210 0.99038 0 27.39496 0.77614 24.58033 0.69640 4.22773 0.30896 3.79298 0.27719 54906.588699 0.000263 0.18537 0.01466 0.98901 0 26.17936 0.80932 23.49222 0.72625 4.85278 0.35317 4.35473 0.31693 54906.589269 0.000307 0.15945 0.01230 1.00000 0 26.78877 0.76873 23.49441 0.67418 4.27141 0.30580 3.74453 0.26806 54906.589834 0.000258 0.18108 0.01424 0.97753 0 28.30410 0.85776 25.04495 0.75889 5.12520 0.37207 4.52792 0.32866 54906.590392 0.000301 0.16318 0.01258 0.97115 0 26.98224 0.77080 24.06958 0.68756 4.40310 0.31521 3.92991 0.28133 54906.590968 0.000275 0.17042 0.01326 1.00000 0 27.23067 0.81048 24.44026 0.72742 4.64052 0.33357 4.16497 0.29938 54906.591790 0.000547 0.14062 0.00832 0.99471 0 28.46817 0.58823 25.20859 0.52083 4.00325 0.22181 3.54459 0.19641
