/* ** ** 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 55249.238702 0.000292 0.34602 0.01310 1.00000 0 62.41812 1.18519 56.13788 1.06585 21.59779 0.70749 19.42397 0.63624 55249.239275 0.000281 0.35011 0.01335 1.00000 0 64.09332 1.23947 58.03420 1.12218 22.43982 0.73744 20.31684 0.66758 55249.239845 0.000289 0.34454 0.01291 1.00000 0 64.05160 1.21546 57.70532 1.09498 22.06856 0.71267 19.88002 0.64192 55249.240404 0.000269 0.37741 0.01436 1.00000 0 62.25377 1.23619 56.52293 1.12240 23.49515 0.76228 21.33254 0.69211 55249.240953 0.000281 0.33821 0.01255 1.00000 0 66.97903 1.25448 60.81393 1.13901 22.65302 0.72603 20.56821 0.65922 55249.241503 0.000269 0.37717 0.01412 1.00000 0 62.96267 1.24041 57.16642 1.12621 23.74756 0.75632 21.56130 0.68669 55249.242039 0.000266 0.36260 0.01361 1.00000 0 66.26004 1.29288 60.16618 1.17397 24.02573 0.77054 21.81595 0.69967 55249.242568 0.000263 0.37780 0.01431 1.00000 0 63.51249 1.25958 57.67997 1.14390 23.99485 0.77434 21.79151 0.70323 55249.243103 0.000272 0.35436 0.01327 1.00000 0 65.71090 1.26034 59.68561 1.14477 23.28502 0.74905 21.14968 0.68036 55249.243644 0.000269 0.35903 0.01370 1.00000 0 64.66644 1.25754 58.72299 1.14196 23.21728 0.76212 21.08371 0.69208 55249.244183 0.000269 0.36831 0.01389 1.00000 0 64.57199 1.26465 58.62165 1.14811 23.78257 0.76678 21.59104 0.69612 55249.244718 0.000266 0.36541 0.01379 1.00000 0 65.34141 1.27621 59.34402 1.15907 23.87631 0.77099 21.68456 0.70021 55249.245250 0.000266 0.36310 0.01366 1.00000 0 65.36275 1.27639 59.36604 1.15928 23.73308 0.76301 21.55539 0.69299 55249.245777 0.000260 0.36734 0.01413 1.00000 0 65.06007 1.27988 59.09415 1.16252 23.89889 0.79035 21.70745 0.71788 55249.246304 0.000266 0.36161 0.01365 1.00000 0 65.69908 1.27526 59.66512 1.15813 23.75734 0.76915 21.57568 0.69852 55249.246845 0.000275 0.35613 0.01345 1.00000 0 64.42218 1.24837 58.49363 1.13348 22.94261 0.74394 20.83108 0.67547 55249.247380 0.000260 0.38075 0.01451 1.00000 0 63.43589 1.27347 57.60468 1.15641 24.15320 0.78275 21.93309 0.71080 55249.247912 0.000272 0.35125 0.01322 1.00000 0 66.23530 1.26626 60.14838 1.14989 23.26526 0.75442 21.12691 0.68508 55249.248471 0.000286 0.35048 0.01320 1.00000 0 62.74747 1.20068 56.97738 1.09027 21.99164 0.71348 19.96918 0.64786 55249.249023 0.000266 0.37045 0.01398 1.00000 0 64.88084 1.27537 58.54086 1.15062 24.03509 0.77454 21.69582 0.69909 55249.249631 0.000341 0.36195 0.01225 1.00000 0 63.76552 1.11358 57.91729 1.01145 23.08007 0.66889 20.96362 0.60755
