/* ** ** 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 57785.500073 0.000281 0.23103 0.01836 0.98969 0 22.29649 0.76556 17.90620 0.61478 5.15109 0.36919 4.13569 0.29634 57785.500631 0.000278 0.22988 0.01826 1.00000 0 22.14219 0.76592 18.03012 0.62346 5.09006 0.36394 4.15656 0.29707 57785.501152 0.000243 0.26554 0.02135 1.00000 0 22.67611 0.84654 17.89194 0.66783 6.02150 0.42869 4.74818 0.33797 57785.501716 0.000321 0.20433 0.01614 0.97297 0 22.22332 0.71632 17.90429 0.57704 4.54089 0.32748 3.65932 0.26395 57785.502315 0.000278 0.23477 0.01903 1.00000 0 21.59435 0.76473 17.45316 0.61800 5.06980 0.36963 4.09968 0.29888 57785.502856 0.000263 0.23490 0.01883 1.00000 0 22.94880 0.80366 18.49351 0.64760 5.39058 0.38882 4.34293 0.31326 57785.503397 0.000278 0.22215 0.01761 1.00000 0 23.09471 0.78412 18.61673 0.63208 5.13050 0.36755 4.13569 0.29634 57785.503930 0.000255 0.25018 0.02030 0.98864 0 22.52847 0.81567 18.08040 0.65444 5.63617 0.40934 4.52168 0.32833 57785.504465 0.000281 0.23824 0.01898 0.98969 0 21.68804 0.76228 17.45535 0.61347 5.16689 0.36934 4.15656 0.29707 57785.505038 0.000292 0.22808 0.01866 0.99010 0 21.16741 0.73655 17.05581 0.59340 4.82791 0.35742 3.87925 0.28738 57785.505657 0.000327 0.19632 0.01546 0.98230 0 22.96384 0.72880 18.32937 0.58172 4.50822 0.32480 3.59816 0.25923 57785.506270 0.000286 0.21252 0.01717 0.98990 0 23.60731 0.78859 18.70471 0.62477 5.01693 0.36918 3.97699 0.29265 57785.506835 0.000278 0.22637 0.01817 0.98958 0 23.21029 0.79701 18.48453 0.63475 5.25411 0.38107 4.18501 0.30349 57785.507422 0.000310 0.21223 0.01694 0.97196 0 22.23512 0.73608 17.81541 0.58979 4.71896 0.34270 3.78256 0.27466 57785.507998 0.000266 0.24064 0.01968 0.98913 0 22.20616 0.79195 17.79199 0.63452 5.34378 0.39326 4.28292 0.31517 57785.508513 0.000249 0.24316 0.01970 1.00000 0 23.80838 0.85093 18.92790 0.67651 5.78935 0.42092 4.59968 0.33444 57785.509028 0.000266 0.24632 0.01963 1.00000 0 22.15792 0.78830 17.69387 0.62948 5.45798 0.38909 4.35906 0.31075 57785.509595 0.000301 0.21186 0.01635 0.97115 0 23.78331 0.76621 19.20244 0.61860 5.03866 0.35332 4.06799 0.28526 57785.510191 0.000295 0.20085 0.01587 0.99020 0 24.33925 0.78424 19.47807 0.62758 4.88847 0.35261 3.91293 0.28224 57785.510770 0.000284 0.21416 0.01751 0.97959 0 23.55482 0.78940 18.77363 0.62918 5.04448 0.37618 4.02192 0.29995 57785.511409 0.000356 0.22217 0.01593 0.99187 0 22.58143 0.69418 17.98092 0.55276 5.01691 0.32509 3.99475 0.25884
