/* ** ** 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 55852.097688 0.000350 0.10852 0.02561 1.00000 0 3.78494 0.28493 3.03269 0.22820 0.41073 0.09189 0.33113 0.07404 55852.098744 0.000706 0.07549 0.01776 0.76641 0 3.43052 0.21310 2.80208 0.17406 0.25895 0.05875 0.21148 0.04799 55852.099902 0.000451 0.08336 0.01939 0.95513 0 3.95831 0.25383 3.22634 0.20689 0.32997 0.07378 0.26890 0.06013 55852.100880 0.000527 0.07132 0.01676 0.98352 0 3.80534 0.23292 3.09922 0.18970 0.27139 0.06159 0.22093 0.05014 55852.101751 0.000344 0.10813 0.02549 0.98319 0 3.88402 0.29039 3.16676 0.23676 0.41999 0.09391 0.34245 0.07657 55852.102590 0.000495 0.07429 0.01746 0.98246 0 3.91559 0.24041 3.18302 0.19542 0.29091 0.06601 0.23540 0.05342 55852.103507 0.000422 0.08490 0.02006 0.97945 0 3.99585 0.26239 3.25797 0.21393 0.33924 0.07698 0.27655 0.06276 55852.104554 0.000625 0.05711 0.01332 0.97222 0 4.04338 0.21765 3.29739 0.17750 0.23091 0.05240 0.18832 0.04273 55852.105723 0.000544 0.06238 0.01480 0.96809 0 4.21670 0.23894 3.43644 0.19473 0.26304 0.06059 0.21443 0.04939 55852.106843 0.000576 0.06497 0.01500 0.98492 0 3.86375 0.22082 3.14640 0.17982 0.25105 0.05614 0.20442 0.04571 55852.107757 0.000339 0.10408 0.02481 0.97436 0 4.09237 0.29840 3.33366 0.24308 0.42593 0.09666 0.34690 0.07872
