/* ** ** 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 56284.169493 0.000567 0.13171 0.01022 0.76646 0 22.03180 0.57943 19.78082 0.52019 2.90182 0.21190 2.60777 0.19045 56284.170500 0.000440 0.12831 0.00988 0.98026 0 23.33056 0.59669 20.72602 0.52999 2.99358 0.21750 2.65613 0.19295 56284.171400 0.000460 0.12037 0.00918 0.98742 0 23.31664 0.57928 20.92076 0.51974 2.80661 0.20231 2.51797 0.18152 56284.172253 0.000394 0.13608 0.01042 0.99265 0 23.97516 0.63270 21.62766 0.57075 3.26257 0.23459 2.94314 0.21163 56284.173104 0.000457 0.12287 0.00934 1.00000 0 22.67608 0.57434 20.45422 0.51806 2.78630 0.19957 2.51331 0.18002 56284.174285 0.000723 0.12492 0.00943 0.61604 0 22.98465 0.57984 20.73257 0.52303 2.87132 0.20434 2.58998 0.18432 56284.175442 0.000434 0.12540 0.00947 0.98667 0 23.82643 0.60030 21.49279 0.54151 2.98777 0.21263 2.69517 0.19181 56284.176443 0.000567 0.10589 0.00814 0.87245 0 23.99913 0.55806 21.64669 0.50336 2.54130 0.18630 2.29226 0.16804 56284.177456 0.000446 0.12618 0.00963 0.99351 0 23.11479 0.58897 20.59913 0.52486 2.91655 0.20973 2.59689 0.18673 56284.178353 0.000451 0.12208 0.00929 0.98718 0 23.62900 0.58912 21.15623 0.52746 2.88455 0.20740 2.58003 0.18552 56284.179241 0.000437 0.12773 0.00977 0.98675 0 23.04275 0.59176 20.77661 0.53355 2.94317 0.21217 2.65316 0.19127 56284.180112 0.000434 0.12460 0.00945 0.98667 0 24.33154 0.61289 21.76607 0.54822 3.03180 0.21692 2.71170 0.19398
