/* ** ** 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 56066.159992 0.000376 0.13248 0.01016 1.00000 0 25.83498 0.67380 22.90963 0.59750 3.42269 0.24689 3.03513 0.21894 56066.160768 0.000399 0.12738 0.00971 0.98551 0 25.88414 0.65735 22.83072 0.57979 3.29703 0.23688 2.91020 0.20909 56066.161549 0.000382 0.13663 0.01047 0.97727 0 25.68391 0.67255 22.57250 0.59103 3.50912 0.25284 3.08026 0.22193 56066.162339 0.000408 0.11962 0.00904 1.00000 0 27.19626 0.67237 23.64861 0.58465 3.25313 0.23222 2.82986 0.20199 56066.163152 0.000405 0.12474 0.00945 1.00000 0 26.33962 0.66173 23.11502 0.58070 3.28567 0.23491 2.88116 0.20599 56066.163962 0.000405 0.11979 0.00908 1.00000 0 26.92066 0.66682 23.73227 0.58779 3.22486 0.23109 2.84136 0.20362 56066.164735 0.000367 0.13649 0.01042 1.00000 0 26.17796 0.69315 22.88068 0.60582 3.57315 0.25574 3.12604 0.22370 56066.165510 0.000408 0.12723 0.00964 0.98582 0 25.96202 0.65912 22.54860 0.57243 3.30308 0.23577 2.87058 0.20490 56066.166361 0.000443 0.11373 0.00873 0.98693 0 26.18150 0.63227 22.86979 0.55226 2.97760 0.21686 2.60205 0.18948 56066.167246 0.000443 0.11989 0.00908 0.98039 0 25.49624 0.62426 22.11458 0.54145 3.05684 0.21907 2.65193 0.19005 56066.168134 0.000446 0.12241 0.00933 0.95455 0 25.17933 0.61945 21.91362 0.53910 3.08230 0.22234 2.68413 0.19362 56066.168997 0.000417 0.12113 0.00918 0.98611 0 26.44996 0.65366 23.18598 0.57296 3.20378 0.22956 2.80134 0.20075 56066.169853 0.000440 0.12184 0.00940 0.98026 0 24.74117 0.61894 21.53473 0.53869 3.01437 0.22008 2.62353 0.19155 56066.170744 0.000451 0.11431 0.00860 0.98718 0 26.01414 0.62598 22.62325 0.54436 2.97375 0.21197 2.58589 0.18431 56066.171578 0.000382 0.13654 0.01053 0.98485 0 25.57661 0.67598 22.15960 0.58567 3.49234 0.25294 3.02574 0.21914 56066.172373 0.000414 0.12673 0.00959 0.97203 0 25.95007 0.65157 22.68003 0.56944 3.28863 0.23474 2.87058 0.20490 56066.173519 0.000732 0.12987 0.00741 0.98814 0 25.28518 0.48475 21.95258 0.42085 3.28387 0.17646 2.85202 0.15324
