/* ** ** 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 57506.955904 0.000284 0.19928 0.01548 1.00000 0 22.69889 0.72217 20.55453 0.65394 4.52351 0.32059 4.09457 0.29017 57506.956451 0.000263 0.21602 0.01702 0.97802 0 22.91702 0.75663 20.73666 0.68459 4.95045 0.35414 4.47709 0.32029 57506.957007 0.000292 0.18858 0.01497 0.99010 0 23.02392 0.72093 20.86262 0.65311 4.34178 0.31660 3.92849 0.28644 57506.957577 0.000278 0.19040 0.01497 1.00000 0 23.84644 0.74789 21.61699 0.67791 4.54041 0.32735 4.11516 0.29656 57506.958147 0.000292 0.18702 0.01470 0.98020 0 23.55573 0.73057 21.34657 0.66204 4.40547 0.31820 3.99652 0.28864 57506.958717 0.000278 0.19935 0.01569 0.98958 0 23.13924 0.74075 20.95057 0.67063 4.61287 0.33158 4.17956 0.30043 57506.959287 0.000292 0.18475 0.01427 0.99010 0 24.14062 0.73453 21.87636 0.66561 4.45995 0.31666 4.04471 0.28716 57506.959837 0.000258 0.20833 0.01669 1.00000 0 23.39794 0.77699 21.17146 0.70308 4.87460 0.35537 4.41404 0.32184 57506.960404 0.000310 0.17347 0.01346 0.99065 0 23.65865 0.70214 21.70210 0.64408 4.10414 0.29425 3.76473 0.26991 57506.960988 0.000275 0.19417 0.01518 1.00000 0 23.70315 0.74814 21.74248 0.68626 4.60242 0.32913 4.22174 0.30190 57506.961558 0.000295 0.18522 0.01440 0.99020 0 23.33015 0.71861 21.27889 0.65541 4.32119 0.30851 3.93922 0.28120 57506.962151 0.000298 0.18439 0.01416 1.00000 0 23.71120 0.72381 21.49449 0.65607 4.37207 0.30819 3.95998 0.27915 57506.962742 0.000292 0.18750 0.01483 0.98020 0 23.22578 0.72045 21.10706 0.65466 4.35478 0.31688 3.96211 0.28827 57506.963323 0.000289 0.18198 0.01400 0.99000 0 24.61873 0.74670 22.37654 0.67868 4.48013 0.31670 4.07344 0.28795 57506.963899 0.000286 0.19353 0.01519 0.98990 0 22.97777 0.72412 20.94293 0.65999 4.44678 0.31960 4.05162 0.29123 57506.964446 0.000260 0.20546 0.01593 0.97778 0 24.64310 0.78573 22.30226 0.71108 5.06323 0.35796 4.58262 0.32395 57506.964984 0.000278 0.19140 0.01489 1.00000 0 23.74151 0.74361 21.76880 0.68182 4.54406 0.32355 4.16525 0.29658 57506.965522 0.000260 0.19966 0.01586 1.00000 0 24.09926 0.77651 21.94658 0.70713 4.81177 0.34923 4.38058 0.31788 57506.966046 0.000263 0.19941 0.01579 0.98901 0 23.91342 0.76547 21.93424 0.70211 4.76857 0.34529 4.37391 0.31672 57506.966833 0.000524 0.19892 0.01137 0.99448 0 22.87862 0.53166 20.98706 0.48770 4.55098 0.23758 4.17470 0.21793
