/* ** ** 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 56699.174890 0.000489 0.18377 0.01476 0.97041 0 30.68181 0.95632 13.42324 0.40642 5.63851 0.41742 2.41109 0.17459 56699.175983 0.000605 0.16852 0.01371 0.97608 0 30.20778 0.91365 11.13279 0.33674 5.09072 0.38462 1.87518 0.14169 56699.177228 0.000639 0.16663 0.01318 0.97738 0 29.46276 0.86968 10.88863 0.32140 4.90942 0.36021 1.81385 0.13309 56699.178559 0.000692 0.15310 0.01207 0.96653 0 29.80899 0.84306 11.02188 0.31172 4.56372 0.33577 1.68740 0.12414 56699.179866 0.000616 0.16714 0.01360 0.97653 0 29.78119 0.89865 11.00791 0.33216 4.97768 0.37609 1.83912 0.13897 56699.181038 0.000556 0.19657 0.01573 0.96875 0 28.99673 0.92767 10.71486 0.34279 5.69985 0.41823 2.10641 0.15455 56699.182375 0.000781 0.16639 0.01317 0.80009 0 29.45575 0.87216 10.90068 0.32277 4.90116 0.35962 1.81365 0.13307 56699.183767 0.000611 0.17294 0.01395 0.98578 0 29.03015 0.89321 10.73276 0.33023 5.02038 0.37431 1.85656 0.13842 56699.185112 0.000735 0.16875 0.01313 0.95276 0 27.25591 0.79452 9.65402 0.28139 4.59943 0.33166 1.63010 0.11754 56699.186658 0.000810 0.15183 0.01137 0.96429 0 28.74756 0.77712 10.16110 0.27468 4.36461 0.30493 1.54288 0.10779
