/* ** ** 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 58889.318746 0.000258 0.15852 0.01246 1.00000 0 30.40130 0.87888 27.72971 0.80164 4.81918 0.35222 4.39961 0.32160 58889.319305 0.000301 0.13688 0.01046 0.99038 0 30.90540 0.81798 28.16525 0.74544 4.23043 0.30314 3.85462 0.27620 58889.319881 0.000275 0.14897 0.01135 1.00000 0 30.97484 0.85782 28.33163 0.78462 4.61423 0.32763 4.21947 0.29958 58889.320439 0.000284 0.14582 0.01113 0.98980 0 31.14091 0.85011 28.34913 0.77383 4.54112 0.32371 4.13436 0.29473 58889.320998 0.000275 0.15007 0.01167 0.97895 0 30.96465 0.85461 28.34321 0.78226 4.64674 0.33787 4.25346 0.30927 58889.321533 0.000260 0.16536 0.01296 1.00000 0 28.86889 0.85112 26.43228 0.77928 4.77387 0.34664 4.37095 0.31738 58889.322048 0.000255 0.16526 0.01272 1.00000 0 29.96382 0.87517 27.42507 0.80102 4.95184 0.35247 4.53235 0.32261 58889.322603 0.000301 0.13305 0.01022 1.00000 0 31.45134 0.83204 28.55434 0.75529 4.18462 0.30181 3.80006 0.27410 58889.323220 0.000315 0.13357 0.01020 0.99083 0 30.37564 0.79862 27.52748 0.72370 4.05730 0.29075 3.67617 0.26341 58889.323839 0.000304 0.13653 0.01063 0.99048 0 30.33842 0.81154 27.60206 0.73838 4.14208 0.30276 3.76505 0.27521 58889.324429 0.000286 0.14394 0.01102 1.00000 0 30.95313 0.83944 28.14713 0.76331 4.45533 0.31886 4.05269 0.29007 58889.325002 0.000286 0.15278 0.01211 0.97980 0 28.60332 0.80796 26.17544 0.73938 4.37002 0.32374 3.99922 0.29627 58889.325555 0.000266 0.15044 0.01165 1.00000 0 31.79907 0.88601 28.70321 0.79966 4.78401 0.34556 4.31948 0.31201 58889.326084 0.000263 0.16947 0.01323 0.98901 0 28.69953 0.85249 26.09011 0.77493 4.86374 0.35127 4.41547 0.31894 58889.326640 0.000292 0.14864 0.01164 1.00000 0 28.66861 0.81978 26.22046 0.74978 4.26128 0.31068 3.89672 0.28408 58889.327172 0.000240 0.18053 0.01502 0.98795 0 28.52417 0.92584 25.57093 0.83000 5.14938 0.39455 4.61979 0.35396 58889.327922 0.000509 0.13118 0.00856 0.97159 0 30.16400 0.65589 27.57308 0.59959 3.95695 0.24343 3.61702 0.22252
