/* ** ** 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 57150.147372 0.000330 0.20897 0.01620 1.00000 0 18.41544 0.59957 16.99128 0.55319 3.84822 0.27076 3.54977 0.24976 57150.148107 0.000405 0.17417 0.01369 0.99286 0 17.75060 0.53461 16.28285 0.49033 3.09166 0.22442 2.83590 0.20584 57150.148871 0.000359 0.18802 0.01454 1.00000 0 18.89643 0.58455 17.21476 0.53252 3.55290 0.25184 3.23594 0.22933 57150.149635 0.000405 0.17106 0.01325 1.00000 0 18.11818 0.53641 16.63546 0.49245 3.09921 0.22176 2.84593 0.20362 57150.150410 0.000370 0.18891 0.01467 1.00000 0 18.21104 0.56389 16.64102 0.51526 3.44021 0.24494 3.14404 0.22381 57150.151142 0.000362 0.18545 0.01471 0.99200 0 18.95976 0.58519 17.11489 0.52822 3.51603 0.25701 3.17232 0.23187 57150.151828 0.000324 0.22915 0.01812 1.00000 0 17.17128 0.58987 15.57239 0.53493 3.93472 0.28019 3.57003 0.25422 57150.152537 0.000385 0.19484 0.01499 0.96992 0 17.47455 0.54350 16.09914 0.50071 3.40473 0.23956 3.13701 0.22072 57150.153301 0.000379 0.18832 0.01476 1.00000 0 17.77256 0.55473 16.09476 0.50231 3.34685 0.24056 3.03067 0.21788 57150.154027 0.000347 0.19560 0.01535 0.99167 0 18.60736 0.59200 17.01313 0.54119 3.63964 0.26109 3.33132 0.23897 57150.154704 0.000330 0.22846 0.01810 0.99123 0 17.03893 0.58574 15.39902 0.52933 3.89278 0.27794 3.52071 0.25134 57150.155410 0.000376 0.19163 0.01499 0.99231 0 17.74080 0.55508 16.12178 0.50441 3.39963 0.24380 3.09318 0.22180 57150.156174 0.000388 0.17217 0.01331 0.99254 0 19.15367 0.56861 17.37799 0.51587 3.29778 0.23544 2.99128 0.21355 57150.156958 0.000396 0.17754 0.01378 0.99270 0 18.27735 0.54931 16.50159 0.49593 3.24487 0.23220 2.92964 0.20961 57150.157748 0.000394 0.17929 0.01396 1.00000 0 18.17053 0.55240 16.37247 0.49772 3.25778 0.23361 2.93397 0.21039 57150.158538 0.000396 0.17305 0.01346 0.98540 0 18.94396 0.56236 16.99465 0.50450 3.27821 0.23568 2.94087 0.21143 57150.159319 0.000385 0.18267 0.01415 0.98496 0 18.46927 0.56249 16.72315 0.50926 3.37380 0.24023 3.05224 0.21735
