/* ** ** 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 59707.208664 0.000289 0.16736 0.01300 1.00000 0 25.48257 0.75147 23.66030 0.69773 4.26476 0.30653 3.95975 0.28461 59707.209246 0.000292 0.16116 0.01251 0.99010 0 26.77481 0.77114 24.59113 0.70821 4.31503 0.31102 3.96415 0.28574 59707.209796 0.000258 0.17868 0.01397 0.98876 0 27.75746 0.84196 25.20766 0.76463 4.95979 0.35743 4.50471 0.32470 59707.210360 0.000307 0.15616 0.01190 1.00000 0 26.48742 0.75153 24.21912 0.68717 4.13625 0.29249 3.77988 0.26728 59707.210959 0.000292 0.17487 0.01337 1.00000 0 25.00210 0.74693 22.93715 0.68524 4.37214 0.30764 4.00667 0.28191 59707.211578 0.000327 0.14581 0.01111 0.99115 0 26.74761 0.73163 24.44831 0.66865 3.90005 0.27732 3.56342 0.25334 59707.212186 0.000281 0.17165 0.01326 0.95876 0 27.47937 0.80392 24.89454 0.72828 4.71696 0.33721 4.27462 0.30557 59707.212764 0.000298 0.16102 0.01247 0.99029 0 26.01149 0.75151 24.09122 0.69601 4.18849 0.30108 3.88211 0.27903 59707.213404 0.000341 0.14120 0.01066 1.00000 0 26.46684 0.70973 24.14397 0.64739 3.73710 0.26361 3.41246 0.24070 59707.214043 0.000298 0.15505 0.01207 1.00000 0 26.75778 0.75988 24.70488 0.70156 4.14871 0.30071 3.83351 0.27783 59707.214645 0.000304 0.15754 0.01225 0.99048 0 26.35698 0.75254 24.21004 0.69116 4.15219 0.30026 3.81591 0.27583 59707.215235 0.000286 0.17663 0.01372 1.00000 0 25.01598 0.76082 22.73265 0.69142 4.41857 0.31590 4.01555 0.28705 59707.215834 0.000312 0.15587 0.01202 0.99074 0 26.59721 0.75431 24.00935 0.68092 4.14563 0.29728 3.74226 0.26835 59707.216401 0.000255 0.19634 0.01530 0.97727 0 25.91617 0.81679 23.62717 0.74457 5.08831 0.36275 4.64584 0.33126 59707.216899 0.000243 0.19568 0.01519 0.98810 0 27.15078 0.85531 24.84883 0.78277 5.31294 0.37699 4.86204 0.34492 59707.217585 0.000443 0.14993 0.00992 0.98039 0 25.79153 0.61363 23.85488 0.56755 3.86703 0.23870 3.57766 0.22085
