/* ** ** 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 59342.154875 0.000787 0.12774 0.00964 0.99632 0 13.39013 0.34295 11.54354 0.29565 1.71042 0.12141 1.47412 0.10463 59342.156368 0.000706 0.13540 0.01026 0.99180 0 14.05933 0.37144 12.19274 0.32213 1.90363 0.13512 1.65077 0.11717 59342.157749 0.000674 0.15310 0.01176 0.98283 0 13.05847 0.36577 11.32786 0.31730 1.99922 0.14300 1.73418 0.12404 59342.159213 0.000790 0.12366 0.00942 0.98535 0 13.72567 0.34858 11.90209 0.30227 1.69732 0.12187 1.47192 0.10569 59342.160717 0.000715 0.13456 0.01042 0.99190 0 13.74948 0.36607 11.92821 0.31757 1.85010 0.13455 1.60501 0.11673 59342.162219 0.000787 0.12760 0.00963 0.97794 0 13.59754 0.34559 11.79353 0.29974 1.73510 0.12332 1.50492 0.10696 59342.163857 0.000851 0.11417 0.00873 0.98639 0 13.74183 0.33646 11.91225 0.29167 1.56885 0.11366 1.36003 0.09853 59342.166018 0.001311 0.12930 0.00779 0.97572 0 12.94139 0.26243 11.22045 0.22754 1.67337 0.09489 1.45087 0.08227
