/* ** ** 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 55678.242729 0.000495 0.09763 0.01466 0.97076 0 6.74952 0.29962 6.09764 0.27068 0.65897 0.09453 0.59681 0.08559 55678.243721 0.000498 0.09499 0.01425 0.98837 0 6.76614 0.29906 6.13944 0.27137 0.64271 0.09217 0.58277 0.08358 55678.244832 0.000613 0.08225 0.01226 0.96698 0 6.46500 0.26282 5.87539 0.23885 0.53177 0.07626 0.48327 0.06931 55678.246021 0.000576 0.08696 0.01282 0.96985 0 6.56639 0.27358 5.96820 0.24866 0.57100 0.08075 0.51900 0.07340 55678.247127 0.000530 0.09163 0.01354 0.98361 0 6.68286 0.28661 6.07330 0.26047 0.61233 0.08660 0.55648 0.07870 55678.248232 0.000576 0.08973 0.01325 0.96985 0 6.36471 0.26983 5.78420 0.24522 0.57109 0.08076 0.51900 0.07340 55678.249112 0.000304 0.06437 0.01536 0.96190 0 6.59439 0.37737 5.99404 0.34302 0.42449 0.09832 0.38585 0.08937 55678.249725 0.000310 0.06639 0.01497 0.99065 0 6.57798 0.37310 5.97870 0.33911 0.43669 0.09529 0.39689 0.08661 55678.250506 0.000472 0.10255 0.01544 1.00000 0 6.52161 0.29921 5.92672 0.27192 0.66880 0.09592 0.60780 0.08717 55678.251591 0.000613 0.08036 0.01170 0.97642 0 6.75832 0.26797 6.14188 0.24353 0.54311 0.07605 0.49358 0.06911 55678.252746 0.000535 0.08722 0.01303 0.98919 0 6.82978 0.28675 6.20678 0.26059 0.59571 0.08543 0.54137 0.07764 55678.253666 0.000385 0.05390 0.01237 0.96241 0 6.38791 0.33055 5.80678 0.30048 0.34431 0.07699 0.31302 0.06999 55678.254609 0.000558 0.08441 0.01244 0.98964 0 6.83407 0.28244 6.21281 0.25677 0.57687 0.08158 0.52443 0.07417 55678.255590 0.000422 0.13131 0.01981 0.99315 0 5.78744 0.30355 5.26090 0.27593 0.75993 0.10747 0.69081 0.09769 55678.256328 0.000315 0.07677 0.01738 0.97248 0 5.68898 0.34385 5.17005 0.31249 0.43672 0.09530 0.39689 0.08661 55678.257480 0.000836 0.08814 0.01086 0.97578 0 6.42580 0.22411 5.83968 0.20367 0.56637 0.06693 0.51471 0.06082
