/* ** ** 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 56300.152077 0.000558 0.08461 0.01246 0.97409 0 6.96544 0.28674 6.29854 0.25929 0.58932 0.08334 0.53280 0.07535 56300.153240 0.000605 0.07636 0.01136 0.98086 0 7.04911 0.28027 6.32096 0.25133 0.53826 0.07718 0.48341 0.06930 56300.154166 0.000321 0.14805 0.02247 0.99099 0 6.84019 0.37677 6.14961 0.33869 1.01270 0.14322 0.91061 0.12878 56300.154872 0.000385 0.10940 0.01739 0.96241 0 7.56127 0.36397 6.78196 0.32636 0.82722 0.12535 0.74081 0.11223 56300.155656 0.000399 0.11914 0.01782 0.97101 0 6.96435 0.33825 6.27028 0.30453 0.82976 0.11735 0.74751 0.10571 56300.156545 0.000489 0.09724 0.01478 0.97633 0 6.85627 0.30511 6.10777 0.27181 0.66668 0.09687 0.59412 0.08634 56300.157439 0.000405 0.10936 0.01630 0.97143 0 7.54612 0.35506 6.74260 0.31724 0.82521 0.11671 0.73652 0.10416 56300.158382 0.000538 0.08126 0.01212 0.98387 0 7.48251 0.30684 6.66614 0.27334 0.60803 0.08719 0.54152 0.07763 56300.159398 0.000477 0.09908 0.01488 0.96970 0 6.97702 0.31297 6.24696 0.28019 0.69128 0.09909 0.61936 0.08879 56300.160410 0.000535 0.09847 0.01347 0.99459 0 7.40512 0.30378 6.56671 0.26938 0.72918 0.09519 0.64745 0.08454
