/* ** ** 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 55578.298169 0.000324 0.10843 0.01657 0.99107 0 9.10411 0.43070 8.15390 0.38571 0.98712 0.14346 0.88308 0.12835 55578.298866 0.000373 0.09653 0.01428 0.96899 0 9.10944 0.39646 8.30123 0.36129 0.87935 0.12436 0.80133 0.11333 55578.299618 0.000379 0.09522 0.01409 0.96947 0 9.17543 0.39889 8.29245 0.36047 0.87370 0.12357 0.78871 0.11154 55578.300391 0.000394 0.09567 0.01439 0.97794 0 8.63483 0.37943 7.86451 0.34557 0.82608 0.11881 0.75207 0.10817 55578.301207 0.000422 0.09428 0.01395 0.96575 0 8.26923 0.35887 7.53482 0.32699 0.77965 0.11026 0.71040 0.10047 55578.302084 0.000454 0.08115 0.01226 0.98726 0 8.61444 0.35531 7.78541 0.32108 0.69904 0.10160 0.63240 0.09191 55578.302949 0.000411 0.08463 0.01248 1.00000 0 9.17650 0.38306 8.32550 0.34753 0.77659 0.10983 0.70540 0.09976 55578.303759 0.000399 0.08922 0.01338 0.98551 0 9.04595 0.38321 8.24318 0.34921 0.80711 0.11609 0.73548 0.10579 55578.304540 0.000382 0.09241 0.01402 0.98485 0 8.95483 0.39123 8.15979 0.35650 0.82748 0.12027 0.75402 0.10959 55578.305284 0.000362 0.09504 0.01445 1.00000 0 9.05497 0.40325 8.25112 0.36745 0.86058 0.12508 0.78418 0.11397 55578.306007 0.000362 0.09637 0.01465 0.98400 0 9.11045 0.40584 8.25863 0.36791 0.87796 0.12759 0.79693 0.11583 55578.306815 0.000446 0.07676 0.01126 0.98052 0 9.48429 0.37214 8.64238 0.33911 0.72797 0.10295 0.66336 0.09381 55578.307631 0.000370 0.08911 0.01302 0.98438 0 10.03075 0.42032 9.11197 0.38181 0.89383 0.12517 0.81087 0.11355 55578.308502 0.000501 0.08888 0.01119 0.97688 0 10.17989 0.36314 9.26632 0.33055 0.90475 0.10919 0.82344 0.09938
