/* ** ** 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 56369.066027 0.000310 0.15615 0.01209 0.99065 0 26.02568 0.72972 24.02862 0.67372 4.06390 0.29319 3.74829 0.27040 56369.066606 0.000269 0.17693 0.01379 1.00000 0 26.41883 0.80089 24.10503 0.73072 4.67424 0.33564 4.26079 0.30587 56369.067150 0.000275 0.17630 0.01364 0.96842 0 26.49990 0.78722 24.52422 0.72853 4.67185 0.33369 4.32310 0.30878 56369.067685 0.000260 0.18062 0.01423 0.98889 0 26.61735 0.81026 24.65799 0.75062 4.80760 0.34940 4.45370 0.32368 56369.068244 0.000298 0.16455 0.01262 0.99029 0 26.07604 0.75172 24.09988 0.69474 4.29072 0.30488 3.96340 0.28163 56369.068811 0.000269 0.16654 0.01286 1.00000 0 28.03448 0.82274 25.69463 0.75403 4.66876 0.33349 4.27661 0.30546 56369.069393 0.000312 0.15375 0.01195 0.99074 0 25.97322 0.72739 24.06109 0.67384 3.99350 0.28954 3.69951 0.26822 56369.070035 0.000330 0.13398 0.01058 0.99123 0 27.51721 0.72919 25.49240 0.67554 3.68683 0.27426 3.41554 0.25408 56369.070672 0.000307 0.14907 0.01151 0.98113 0 27.66334 0.75909 25.62720 0.70322 4.12390 0.29749 3.82037 0.27560 56369.071268 0.000289 0.16625 0.01281 0.98000 0 26.35216 0.76230 24.41218 0.70618 4.38093 0.31291 4.05842 0.28987 56369.071867 0.000310 0.16134 0.01244 0.99065 0 25.13684 0.71907 23.28642 0.66614 4.05570 0.29040 3.75714 0.26902 56369.072460 0.000284 0.16284 0.01266 0.98980 0 26.97980 0.78044 24.99394 0.72299 4.39329 0.31698 4.06992 0.29365 56369.073047 0.000304 0.14671 0.01116 1.00000 0 28.32886 0.77072 26.24352 0.71399 4.15610 0.29533 3.85016 0.27359 56369.073640 0.000289 0.16112 0.01238 1.00000 0 26.78010 0.77077 24.80868 0.71403 4.31492 0.30741 3.99728 0.28478 56369.074245 0.000315 0.14342 0.01122 1.00000 0 26.95485 0.73881 24.97098 0.68444 3.86591 0.28321 3.58137 0.26236 56369.074856 0.000295 0.16280 0.01246 1.00000 0 26.24510 0.75660 24.31339 0.70091 4.27266 0.30287 3.95818 0.28058 56369.075455 0.000304 0.15416 0.01195 0.99048 0 27.06468 0.75740 24.81807 0.69449 4.17229 0.30166 3.82549 0.27663 56369.076022 0.000263 0.17330 0.01369 1.00000 0 26.90238 0.80927 24.87823 0.74839 4.66207 0.34061 4.31179 0.31503 56369.076667 0.000382 0.17251 0.01140 0.98485 0 26.44534 0.66698 24.38842 0.61508 4.56196 0.27868 4.20797 0.25701
