/* ** ** 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 56012.089305 0.000402 0.16109 0.02276 0.94245 0 17.27962 0.88118 5.91522 0.30146 2.78359 0.36668 0.94644 0.12481 56012.090877 0.001169 0.17461 0.01373 0.97525 0 16.93024 0.50976 5.71561 0.17210 2.95620 0.21472 0.99828 0.07252 56012.092344 0.000298 0.16177 0.02563 0.98058 0 17.62331 1.03870 5.93507 0.34981 2.85084 0.41927 0.96089 0.14138 56012.093125 0.000483 0.17605 0.02182 0.95210 0 16.78823 0.79829 5.58595 0.26550 2.95552 0.33820 0.98230 0.11237 56012.094114 0.000506 0.16221 0.01940 0.96571 0 17.89378 0.80466 6.06892 0.27289 2.90260 0.32171 0.98345 0.10899 56012.096044 0.001424 0.17509 0.01248 0.95629 0 16.86243 0.46001 5.75797 0.15708 2.95247 0.19439 1.00850 0.06640
