/* ** ** 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 58130.160220 0.000417 0.30935 0.01155 1.00000 0 51.30354 0.92334 44.14747 0.79436 15.87050 0.51922 13.65331 0.44661 58130.161053 0.000417 0.30025 0.01111 1.00000 0 52.31081 0.92871 45.69591 0.81116 15.70629 0.50964 13.71623 0.44513 58130.161872 0.000402 0.30590 0.01130 1.00000 0 54.15299 0.97265 46.64673 0.83777 16.56545 0.53458 14.26749 0.46034 58130.162700 0.000425 0.29449 0.01076 1.00000 0 53.12069 0.92708 46.06091 0.80390 15.64340 0.50241 13.56608 0.43565 58130.163568 0.000443 0.27966 0.01024 1.00000 0 52.99623 0.91365 46.25725 0.79745 14.82113 0.47868 12.93578 0.41781 58130.164424 0.000414 0.29614 0.01103 1.00000 0 53.14950 0.93995 46.46896 0.82167 15.73947 0.51568 13.75569 0.45066 58130.165223 0.000385 0.32455 0.01213 1.00000 0 52.04143 0.96295 45.66418 0.84494 16.88989 0.54871 14.82053 0.48147 58130.166015 0.000408 0.30139 0.01115 1.00000 0 53.45889 0.95549 46.47392 0.83054 16.11189 0.52208 14.00107 0.45365 58130.166823 0.000399 0.30813 0.01153 1.00000 0 52.64190 0.95141 46.21264 0.83522 16.22031 0.53169 14.23957 0.46676 58130.167636 0.000414 0.30322 0.01128 0.99301 0 52.33092 0.93471 45.71386 0.81655 15.86782 0.51772 13.86688 0.45240 58130.168727 0.000677 0.31291 0.00897 1.00000 0 51.74101 0.72630 45.41526 0.63750 16.19008 0.40456 14.21066 0.35510
