/* ** ** 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 60106.137850 0.000420 0.17081 0.01332 0.98621 0 17.71160 0.52466 16.16161 0.47873 3.02538 0.21817 2.76396 0.19933 60106.138701 0.000431 0.16570 0.01280 0.99329 0 17.96537 0.52551 16.26982 0.47594 2.97685 0.21280 2.69633 0.19268 60106.139618 0.000486 0.14657 0.01139 0.97024 0 18.20482 0.49937 16.55500 0.45414 2.66830 0.19399 2.42724 0.17643 60106.140625 0.000521 0.13605 0.01080 0.99444 0 17.40078 0.47339 15.83913 0.43087 2.36739 0.17649 2.15761 0.16083 60106.141580 0.000434 0.16018 0.01246 0.99333 0 18.41058 0.53283 16.63662 0.48145 2.94896 0.21302 2.66743 0.19262 60106.142497 0.000483 0.15474 0.01204 1.00000 0 17.00711 0.48673 15.31278 0.43823 2.63176 0.19049 2.36792 0.17144 60106.143478 0.000498 0.15091 0.01180 0.98256 0 17.03381 0.47472 15.36328 0.42812 2.57065 0.18786 2.31736 0.16934 60106.144407 0.000431 0.16773 0.01300 1.00000 0 17.67940 0.52158 15.86930 0.46820 2.96531 0.21246 2.66479 0.19092 60106.145321 0.000483 0.15837 0.01240 0.98802 0 16.87119 0.48177 15.06454 0.43018 2.67181 0.19472 2.38568 0.17387 60106.146505 0.000700 0.14935 0.00968 0.98760 0 17.47290 0.40823 15.74098 0.36774 2.60958 0.15775 2.35029 0.14207
