/* ** ** 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 55265.984267 0.000388 0.30898 0.01135 1.00000 0 54.81194 0.97863 48.04420 0.85778 16.93597 0.54345 14.84605 0.47640 55265.985063 0.000408 0.29236 0.01091 0.99291 0 55.05386 0.96380 47.95294 0.83936 16.09580 0.53073 14.01738 0.46213 55265.985862 0.000391 0.30172 0.01122 1.00000 0 55.40447 0.98545 48.45541 0.86184 16.71643 0.54570 14.61045 0.47696 55265.986626 0.000373 0.31749 0.01184 1.00000 0 55.34848 1.01685 48.17640 0.88502 17.57266 0.57045 15.29754 0.49655 55265.987395 0.000396 0.29687 0.01111 1.00000 0 55.74826 0.98846 48.29558 0.85631 16.55015 0.54537 14.33895 0.47248 55265.988188 0.000396 0.30212 0.01124 1.00000 0 55.33448 0.98637 47.48498 0.84645 16.71741 0.54577 14.34591 0.46835 55265.988969 0.000385 0.31408 0.01161 1.00000 0 54.76997 0.99299 47.45192 0.86019 17.20204 0.55403 14.90503 0.48004 55265.989739 0.000385 0.30056 0.01110 0.99248 0 57.94280 1.02723 49.77426 0.88239 17.41505 0.56408 14.95739 0.48450 55265.990512 0.000388 0.30649 0.01138 1.00000 0 55.16180 0.99185 48.00665 0.86320 16.90647 0.54914 14.71179 0.47779 55265.991287 0.000388 0.30402 0.01123 1.00000 0 56.62114 1.01692 48.58722 0.87263 17.21405 0.55585 14.77144 0.47698 55265.992077 0.000402 0.30511 0.01120 0.98569 0 54.83875 0.97478 47.48802 0.84404 16.73168 0.53753 14.49051 0.46547 55265.992870 0.000391 0.30317 0.01114 1.00000 0 56.68977 1.00559 48.65717 0.86310 17.18650 0.55323 14.75106 0.47484 55265.993657 0.000396 0.30374 0.01126 1.00000 0 55.39656 0.99018 47.54433 0.84983 16.82620 0.54644 14.44088 0.46898 55265.994574 0.000521 0.30660 0.00976 1.00000 0 55.79103 0.86038 48.36159 0.74579 17.10533 0.47648 14.82533 0.41297
