/* ** ** 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 56720.379052 0.000234 0.19270 0.01520 0.98765 0 30.12142 0.94496 25.55167 0.80151 5.80438 0.42024 4.93300 0.35705 56720.379576 0.000289 0.15770 0.01208 1.00000 0 30.41985 0.86216 25.42729 0.72065 4.79721 0.34127 4.01232 0.28542 56720.380160 0.000295 0.15359 0.01191 0.99020 0 29.85923 0.83885 25.39694 0.71349 4.58600 0.33157 3.89885 0.28189 56720.380713 0.000258 0.17344 0.01344 0.98876 0 30.54180 0.90621 26.08208 0.77388 5.29732 0.37918 4.52365 0.32380 56720.381213 0.000243 0.19023 0.01499 0.98810 0 29.51642 0.92137 24.98795 0.77998 5.61501 0.40637 4.75470 0.34414 56720.381740 0.000284 0.16470 0.01265 0.98980 0 29.60168 0.85357 25.16958 0.72577 4.87540 0.34721 4.14524 0.29521 56720.382284 0.000260 0.16587 0.01302 0.98889 0 31.17248 0.91234 26.51894 0.77614 5.17054 0.37663 4.39876 0.32041 56720.382796 0.000252 0.17557 0.01348 0.98851 0 31.46994 0.93507 26.57555 0.78960 5.52503 0.39114 4.66887 0.33053 56720.383291 0.000243 0.18724 0.01449 0.97619 0 30.72541 0.93804 26.13268 0.79782 5.75301 0.40925 4.89307 0.34807 56720.383771 0.000237 0.18760 0.01484 1.00000 0 30.39403 0.95495 25.53391 0.80227 5.70193 0.41378 4.78825 0.34748 56720.384223 0.000214 0.21190 0.01680 1.00000 0 29.73942 0.98572 25.17668 0.83447 6.30164 0.45391 5.33691 0.38442 56720.384709 0.000272 0.16573 0.01279 0.98936 0 30.69025 0.89223 25.76295 0.74888 5.08616 0.36372 4.27124 0.30539 56720.385261 0.000281 0.15226 0.01169 1.00000 0 31.60771 0.88319 26.89574 0.75153 4.81256 0.34409 4.09511 0.29279 56720.385803 0.000260 0.16552 0.01292 1.00000 0 31.13467 0.91237 26.49316 0.77636 5.15326 0.37299 4.38489 0.31738 56720.386306 0.000243 0.18207 0.01438 1.00000 0 30.47512 0.93662 25.75001 0.79135 5.54848 0.40365 4.69463 0.34143 56720.386798 0.000249 0.17438 0.01361 1.00000 0 31.40434 0.94586 26.27864 0.79143 5.47616 0.39442 4.59222 0.33078 56720.387316 0.000269 0.16838 0.01325 1.00000 0 29.62031 0.87644 25.06942 0.74173 4.98737 0.36373 4.21877 0.30763 56720.387842 0.000258 0.17373 0.01357 0.98876 0 30.91502 0.92168 25.91611 0.77265 5.37090 0.38774 4.50731 0.32539 56720.388331 0.000231 0.19676 0.01546 1.00000 0 30.34533 0.96606 25.22798 0.80309 5.97070 0.42903 4.96168 0.35647 56720.388838 0.000269 0.17061 0.01330 1.00000 0 29.52118 0.86915 25.02761 0.73681 5.03650 0.36364 4.26498 0.30789 56720.389336 0.000229 0.19698 0.01538 1.00000 0 30.33742 0.96954 25.58413 0.81755 5.97579 0.42579 5.04269 0.35921 56720.389917 0.000353 0.18791 0.01204 0.99180 0 30.65001 0.78144 25.80166 0.65774 5.75937 0.33869 4.84624 0.28500
