/* ** ** 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 57152.148908 0.000324 0.18586 0.01459 1.00000 0 21.19849 0.65532 18.98166 0.58672 3.93992 0.28437 3.53475 0.25503 57152.149521 0.000289 0.21539 0.01687 0.98000 0 20.81625 0.68662 18.93758 0.62465 4.48357 0.31848 4.07461 0.28943 57152.150155 0.000344 0.18458 0.01430 1.00000 0 20.26612 0.62582 18.16826 0.56095 3.74067 0.26573 3.35556 0.23835 57152.150826 0.000327 0.18111 0.01412 1.00000 0 21.41821 0.65569 19.38674 0.59348 3.87915 0.27804 3.50974 0.25158 57152.151440 0.000286 0.22046 0.01719 0.97980 0 20.72609 0.68862 18.83802 0.62588 4.56918 0.32230 4.15124 0.29281 57152.152041 0.000315 0.19081 0.01475 1.00000 0 21.34910 0.66722 19.38677 0.60583 4.07369 0.28797 3.70017 0.26151 57152.152655 0.000298 0.20598 0.01650 0.99029 0 20.76484 0.67708 18.65040 0.60812 4.27723 0.31284 3.84142 0.28098 57152.153280 0.000327 0.17955 0.01387 1.00000 0 21.98915 0.66378 19.87022 0.59981 3.94809 0.28082 3.56292 0.25345 57152.153896 0.000289 0.22059 0.01744 0.98000 0 20.63804 0.68886 18.34542 0.61233 4.55255 0.32633 4.04694 0.29009 57152.154498 0.000312 0.19567 0.01555 1.00000 0 20.58992 0.65568 18.59058 0.59199 4.02882 0.29335 3.64056 0.26507 57152.155094 0.000284 0.21507 0.01715 1.00000 0 20.86488 0.69847 18.70908 0.62626 4.48748 0.32467 4.01927 0.29075 57152.155684 0.000307 0.19865 0.01575 0.99057 0 21.04240 0.67428 18.90480 0.60571 4.18003 0.30306 3.75749 0.27234 57152.156304 0.000312 0.19033 0.01494 0.99074 0 21.61540 0.67753 19.53600 0.61230 4.11402 0.29614 3.71865 0.26760 57152.156931 0.000315 0.18632 0.01439 1.00000 0 21.89761 0.67384 19.90072 0.61237 4.08007 0.28896 3.70611 0.26245 57152.157554 0.000307 0.19119 0.01505 1.00000 0 21.48295 0.67476 19.53557 0.61355 4.10728 0.29637 3.73483 0.26947 57152.158181 0.000321 0.18577 0.01475 0.98198 0 21.48908 0.66531 19.35033 0.59901 3.99194 0.29196 3.59473 0.26293 57152.158812 0.000310 0.19611 0.01545 1.00000 0 20.93976 0.66893 18.81484 0.60105 4.10641 0.29572 3.69387 0.26599 57152.159460 0.000339 0.18427 0.01416 0.96581 0 21.25241 0.64034 19.27698 0.58079 3.91626 0.27693 3.54573 0.25072 57152.160097 0.000298 0.19638 0.01542 0.99029 0 22.05994 0.69975 19.82765 0.62893 4.33210 0.31125 3.89459 0.27972 57152.160734 0.000339 0.20590 0.01500 1.00000 0 21.80961 0.65287 19.46747 0.58274 4.49066 0.29833 4.01118 0.26648
