/* ** ** 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 60102.897282 0.000356 0.18397 0.01458 1.00000 0 18.98020 0.59147 17.38443 0.54179 3.49182 0.25439 3.20067 0.23321 60102.897985 0.000347 0.18508 0.01443 0.97500 0 20.04905 0.61741 18.33569 0.56463 3.71074 0.26582 3.39378 0.24312 60102.898665 0.000333 0.18924 0.01489 0.99130 0 20.13764 0.63454 18.31395 0.57695 3.81078 0.27484 3.46732 0.25002 60102.899337 0.000339 0.19510 0.01512 1.00000 0 19.41418 0.61601 17.55402 0.55702 3.78773 0.26785 3.42450 0.24215 60102.900034 0.000359 0.18025 0.01421 0.99194 0 19.59099 0.60249 17.72353 0.54498 3.53132 0.25634 3.19900 0.23218 60102.900751 0.000359 0.18953 0.01506 1.00000 0 18.54489 0.58477 16.83691 0.53095 3.51472 0.25641 3.19268 0.23291 60102.901478 0.000367 0.18552 0.01462 0.99213 0 18.67942 0.58203 16.95298 0.52822 3.46539 0.25088 3.13873 0.22721 60102.902161 0.000315 0.20947 0.01646 1.00000 0 19.37697 0.64411 17.45980 0.58031 4.05891 0.28893 3.65935 0.26044 60102.902789 0.000312 0.20092 0.01580 0.99074 0 20.33276 0.66009 18.46743 0.59957 4.08528 0.29266 3.71095 0.26584 60102.903425 0.000324 0.19780 0.01565 1.00000 0 19.57828 0.63799 17.84916 0.58157 3.87256 0.27929 3.52924 0.25448 60102.904114 0.000365 0.16927 0.01328 0.99206 0 20.58643 0.61119 18.58359 0.55172 3.48466 0.25296 3.14781 0.22847 60102.904805 0.000327 0.19419 0.01531 0.99115 0 20.03831 0.63956 18.17592 0.58013 3.89121 0.28060 3.52924 0.25448 60102.905459 0.000327 0.19752 0.01576 0.99115 0 19.67999 0.63268 17.69616 0.56887 3.88720 0.28392 3.49714 0.25549 60102.906145 0.000359 0.18005 0.01447 1.00000 0 19.10441 0.59536 17.38443 0.54179 3.43982 0.25472 3.12971 0.23168 60102.907071 0.000567 0.19867 0.01203 0.98469 0 19.19072 0.47592 17.47351 0.43324 3.81268 0.21061 3.47118 0.19174
