/* ** ** 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 57112.022006 0.000295 0.28054 0.01023 1.00000 0 74.71654 1.27153 69.15360 1.17683 20.96103 0.67621 19.39005 0.62553 57112.022590 0.000289 0.27909 0.01015 1.00000 0 77.69214 1.32535 71.03442 1.21172 21.68300 0.69646 19.83017 0.63697 57112.023172 0.000292 0.29343 0.01079 1.00000 0 72.28889 1.26525 66.93231 1.17145 21.21187 0.68637 19.64316 0.63548 57112.023768 0.000304 0.27347 0.00987 1.00000 0 74.90057 1.25753 69.75748 1.17118 20.48314 0.65457 19.07667 0.60963 57112.024393 0.000321 0.25318 0.00924 1.00000 0 75.32798 1.22928 70.15137 1.14480 19.07175 0.62266 17.76117 0.57987 57112.025012 0.000298 0.27315 0.00986 1.00000 0 76.30083 1.27749 71.05551 1.18967 20.84126 0.66670 19.40820 0.62086 57112.025617 0.000307 0.26322 0.00958 1.00000 0 76.50942 1.27093 70.83831 1.17662 20.13863 0.65190 18.64678 0.60353 57112.026230 0.000307 0.26711 0.00967 1.00000 0 75.40654 1.25806 70.22777 1.17166 20.14194 0.64704 18.75862 0.60260 57112.026829 0.000292 0.27855 0.01012 1.00000 0 75.88734 1.29012 70.67690 1.20154 21.13866 0.67906 19.68727 0.63244 57112.027411 0.000289 0.27237 0.00993 1.00000 0 78.26511 1.31273 72.89114 1.22259 21.31722 0.69040 19.85349 0.64300 57112.028004 0.000304 0.26609 0.00973 1.00000 0 75.81338 1.26144 70.60778 1.17483 20.17293 0.65647 18.78777 0.61140 57112.028617 0.000310 0.25779 0.00935 1.00000 0 77.01884 1.26252 71.72980 1.17582 19.85468 0.64229 18.49123 0.59818 57112.029237 0.000310 0.25613 0.00923 1.00000 0 77.67071 1.26285 72.33572 1.17611 19.89362 0.64006 18.52714 0.59609 57112.029859 0.000312 0.26243 0.00958 1.00000 0 74.88830 1.24130 69.74464 1.15604 19.65284 0.63887 18.30299 0.59499 57112.030472 0.000301 0.27346 0.00993 1.00000 0 75.68507 1.27373 70.05169 1.17891 20.69677 0.66607 19.16537 0.61673 57112.031088 0.000315 0.25790 0.00928 1.00000 0 76.05157 1.24140 70.82658 1.15611 19.61384 0.62872 18.26634 0.58553 57112.031708 0.000304 0.27208 0.00982 1.00000 0 75.00393 1.25838 69.85379 1.17197 20.40742 0.65242 19.00620 0.60762 57112.032312 0.000301 0.27789 0.01011 1.00000 0 74.05466 1.25570 68.96845 1.16946 20.57876 0.66221 19.16537 0.61673 57112.032917 0.000304 0.27659 0.00997 1.00000 0 74.20377 1.24457 69.10802 1.15910 20.52425 0.65522 19.11483 0.61022 57112.033623 0.000402 0.25488 0.00811 1.00000 0 77.20732 1.10764 71.90533 1.03158 19.67879 0.55899 18.32740 0.52060
