/* ** ** 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 58150.868221 0.000527 0.21775 0.00783 1.00000 0 56.24863 0.84502 49.82751 0.74860 12.24830 0.39985 10.84638 0.35406 58150.869274 0.000527 0.22050 0.00785 1.00000 0 56.46042 0.85240 49.47234 0.74684 12.44950 0.40149 10.90744 0.35176 58150.870325 0.000524 0.21731 0.00787 1.00000 0 56.48626 0.85536 49.72976 0.75305 12.27485 0.40410 10.80648 0.35576 58150.871398 0.000550 0.21213 0.00752 0.99474 0 56.41201 0.83865 49.66559 0.73835 11.96665 0.38533 10.53526 0.33923 58150.872483 0.000535 0.21417 0.00765 0.99459 0 57.07661 0.85273 50.22122 0.75031 12.22437 0.39631 10.75601 0.34871 58150.873531 0.000512 0.22930 0.00820 1.00000 0 55.86394 0.86654 49.13390 0.76215 12.80952 0.41290 11.26638 0.36316 58150.874575 0.000532 0.21613 0.00772 1.00000 0 56.49354 0.85076 49.64198 0.74758 12.20995 0.39563 10.72890 0.34764 58150.875649 0.000541 0.21429 0.00769 1.00000 0 56.24469 0.84430 49.30403 0.74009 12.05282 0.39260 10.56183 0.34404 58150.876746 0.000556 0.20860 0.00751 1.00000 0 55.79007 0.82698 49.08874 0.72764 11.63782 0.38210 10.23953 0.33619 58150.877816 0.000515 0.22690 0.00816 1.00000 0 55.68530 0.86106 48.79502 0.75449 12.63512 0.41050 11.07355 0.35976 58150.878849 0.000518 0.22269 0.00813 1.00000 0 55.78191 0.85523 49.04498 0.75194 12.42190 0.41131 10.92131 0.36162 58150.879952 0.000584 0.21214 0.00742 0.99505 0 55.48579 0.80787 48.76324 0.70998 11.77070 0.37459 10.34426 0.32919
