/* ** ** Swift/XRT hardness ratio for 4U 1608-52. ** 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 58334.195134 0.000284 1.39677 0.16752 0.97959 0 5.71506 0.53012 2.75845 0.25102 7.98262 0.60687 4.01282 0.29803 58334.195712 0.000295 1.69072 0.20604 0.99020 0 5.07355 0.49467 2.29426 0.22202 8.57794 0.62716 3.89459 0.28393 58334.196265 0.000258 1.89681 0.24198 1.00000 0 4.46041 0.47133 2.40355 0.25377 8.46056 0.60468 4.54443 0.32472 58334.196766 0.000243 2.07849 0.26906 1.00000 0 4.27897 0.46163 2.28471 0.24655 8.89381 0.63626 4.75629 0.34007 58334.197237 0.000229 2.27332 0.30721 1.00000 0 4.20303 0.48291 2.24328 0.25774 9.55482 0.67979 5.10804 0.36336 58334.197732 0.000266 1.93412 0.24177 0.96739 0 4.22271 0.43314 2.31199 0.23690 8.16721 0.58353 4.47814 0.31996 58334.198256 0.000258 2.04564 0.26945 0.96629 0 4.13871 0.45421 2.21341 0.24286 8.46630 0.61669 4.58585 0.33323 58334.198759 0.000246 2.30107 0.31587 0.98824 0 3.86928 0.45154 2.06291 0.24044 8.90350 0.64355 4.73113 0.34178 58334.199283 0.000278 1.57907 0.19169 0.98958 0 4.75012 0.45876 2.58831 0.24997 7.50080 0.55163 4.08756 0.30058 58334.199856 0.000295 1.41865 0.16486 0.98039 0 5.21040 0.46434 2.72850 0.24297 7.39176 0.55133 3.85176 0.28717 58334.200417 0.000266 1.85224 0.23581 0.95652 0 4.51770 0.46938 2.36735 0.24553 8.36785 0.61564 4.41270 0.32449 58334.200953 0.000269 2.07109 0.27341 0.98925 0 3.78009 0.41489 2.04687 0.22457 7.82890 0.57427 4.23203 0.31018 58334.201497 0.000275 1.68702 0.20630 1.00000 0 4.64627 0.45690 2.44061 0.23979 7.83836 0.56981 4.14114 0.30073 58334.202009 0.000237 2.35163 0.31058 0.96341 0 4.20853 0.46778 2.15603 0.23964 9.89690 0.70592 5.08268 0.36248 58334.202521 0.000275 1.44491 0.16866 0.97895 0 5.39361 0.48436 2.85950 0.25684 7.79326 0.58113 4.13120 0.30784 58334.203065 0.000269 1.90861 0.24609 0.98925 0 4.05902 0.42913 2.20510 0.23287 7.74711 0.57183 4.20966 0.31058 58334.203583 0.000249 2.47755 0.34704 1.00000 0 3.62932 0.43427 1.84347 0.22039 8.99180 0.65480 4.55122 0.33139 58334.204141 0.000310 1.76481 0.21437 0.97196 0 4.17518 0.40786 2.17191 0.21174 7.36838 0.53200 3.81193 0.27520 58334.204700 0.000249 1.88825 0.24233 0.98837 0 4.65196 0.49200 2.44997 0.25923 8.78407 0.63856 4.63980 0.33715 58334.205247 0.000298 1.45334 0.17156 0.98058 0 5.06308 0.46902 2.65769 0.24596 7.35836 0.53839 3.87476 0.28323 58334.205843 0.000298 1.62320 0.19483 1.00000 0 4.52705 0.43119 2.33528 0.22245 7.34830 0.53670 3.79006 0.27687 58334.206534 0.000394 1.68674 0.17652 0.99265 0 4.48898 0.37566 2.38522 0.19928 7.57174 0.47581 4.02426 0.25230
