/* ** ** 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 55705.199559 0.000353 0.19408 0.01522 0.99180 0 18.39460 0.57819 16.90719 0.53138 3.57001 0.25656 3.28203 0.23584 55705.200315 0.000402 0.15692 0.01215 0.99281 0 19.93293 0.56702 18.24118 0.51889 3.12791 0.22532 2.86321 0.20628 55705.201122 0.000405 0.16534 0.01275 1.00000 0 18.59588 0.54162 17.18973 0.50066 3.07458 0.21944 2.84211 0.20285 55705.201857 0.000330 0.20509 0.01618 1.00000 0 18.37546 0.59727 16.98547 0.55209 3.76862 0.27081 3.48356 0.25033 55705.202551 0.000365 0.18185 0.01423 0.98413 0 18.95566 0.57756 17.52219 0.53388 3.44716 0.24835 3.18647 0.22957 55705.203286 0.000370 0.17907 0.01413 1.00000 0 18.52044 0.56825 17.11767 0.52521 3.31649 0.24120 3.06524 0.22292 55705.204027 0.000370 0.17463 0.01351 0.99219 0 19.40836 0.57964 17.94032 0.53579 3.38935 0.24191 3.13303 0.22362 55705.204756 0.000359 0.18046 0.01407 1.00000 0 19.16889 0.58614 17.71942 0.54182 3.45918 0.24805 3.19765 0.22930 55705.205511 0.000396 0.17078 0.01325 0.99270 0 18.46472 0.54676 17.07151 0.50550 3.15347 0.22613 2.91551 0.20907 55705.206310 0.000402 0.16284 0.01253 0.99281 0 19.15090 0.55151 17.70625 0.50990 3.11855 0.22258 2.88330 0.20579 55705.207140 0.000428 0.16168 0.01243 0.99324 0 18.22723 0.52274 16.85181 0.48329 2.94699 0.21025 2.72460 0.19438 55705.207994 0.000425 0.16110 0.01245 0.97279 0 18.64458 0.52944 17.23847 0.48951 3.00364 0.21584 2.77711 0.19956 55705.208796 0.000376 0.17414 0.01338 0.99231 0 19.31980 0.57456 17.86288 0.53123 3.36444 0.23841 3.11073 0.22043 55705.209519 0.000347 0.19058 0.01479 1.00000 0 18.88341 0.58967 17.45900 0.54519 3.59882 0.25566 3.32734 0.23638 55705.210242 0.000376 0.18616 0.01465 0.99231 0 17.73340 0.54848 16.39587 0.50711 3.30120 0.23896 3.05222 0.22093 55705.211212 0.000593 0.16684 0.01062 0.99512 0 18.60456 0.44675 17.20140 0.41306 3.10390 0.18302 2.86980 0.16922
