/* ** ** 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 59733.148022 0.000310 0.15421 0.01190 1.00000 0 28.12490 0.80008 24.05148 0.68358 4.33718 0.31106 3.71060 0.26587 59733.148659 0.000327 0.14904 0.01130 0.99115 0 28.42221 0.78748 24.17784 0.66970 4.23591 0.29881 3.59526 0.25359 59733.149293 0.000307 0.15186 0.01182 1.00000 0 29.01255 0.81981 24.69505 0.69778 4.40575 0.31946 3.75089 0.27199 59733.149860 0.000260 0.18844 0.01464 1.00000 0 27.66715 0.87277 23.62402 0.74526 5.21365 0.37017 4.45393 0.31622 59733.150404 0.000284 0.16872 0.01337 0.98980 0 28.05448 0.83746 23.93783 0.71457 4.73338 0.34734 4.03889 0.29638 59733.151017 0.000330 0.14522 0.01104 1.00000 0 28.67451 0.78289 24.46807 0.66804 4.16406 0.29534 3.55304 0.25200 59733.151657 0.000310 0.14727 0.01153 0.99065 0 29.43326 0.82562 25.08274 0.70359 4.33471 0.31683 3.69420 0.27001 59733.152296 0.000330 0.14803 0.01151 0.98246 0 27.80554 0.77405 23.73341 0.66069 4.11600 0.29885 3.51251 0.25503 59733.152881 0.000255 0.19272 0.01534 0.97727 0 27.65508 0.87133 23.62611 0.74439 5.32967 0.38955 4.55331 0.33280 59733.153413 0.000278 0.18003 0.01406 0.96875 0 27.81164 0.84364 23.72677 0.71974 5.00690 0.36020 4.27119 0.30727 59733.154287 0.000596 0.13777 0.00824 0.98678 0 27.73268 0.57149 23.65617 0.48749 3.82069 0.21443 3.25959 0.18294 59733.351714 0.000353 0.13979 0.01084 0.99180 0 27.30564 0.74381 23.22640 0.63230 3.81701 0.27726 3.25099 0.23608 59733.352478 0.000411 0.11780 0.00903 0.98592 0 27.68723 0.68123 24.23690 0.59632 3.26151 0.23684 2.85527 0.20735 59733.353216 0.000327 0.14515 0.01121 0.99115 0 28.03092 0.77495 24.30259 0.67186 4.06858 0.29351 3.52851 0.25453 59733.354179 0.000637 0.13498 0.00776 0.99091 0 27.52509 0.54566 23.84072 0.47258 3.71537 0.20043 3.21964 0.17371
