/* ** ** 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 57786.231500 0.000582 0.17565 0.01391 0.99005 0 13.11587 0.39731 11.18832 0.33888 2.30380 0.16850 1.96718 0.14386 57786.232632 0.000550 0.18228 0.01477 0.98421 0 13.12134 0.41184 11.38723 0.35741 2.39174 0.17873 2.07550 0.15509 57786.233824 0.000642 0.16384 0.01321 0.95946 0 12.68157 0.37030 11.00667 0.32139 2.07778 0.15613 1.80334 0.13551 57786.235094 0.000628 0.15291 0.01191 0.97696 0 13.97772 0.39293 12.13172 0.34104 2.13737 0.15526 1.85523 0.13476 57786.236356 0.000634 0.15330 0.01202 0.98630 0 13.61927 0.38553 11.82202 0.33465 2.08782 0.15268 1.81236 0.13254 57786.237632 0.000642 0.15610 0.01186 0.98198 0 13.62596 0.38444 11.83302 0.33386 2.12697 0.15002 1.84711 0.13029 57786.238815 0.000541 0.19128 0.01536 0.98930 0 12.67827 0.40598 11.01070 0.35258 2.42504 0.17855 2.10611 0.15507 57786.240511 0.001155 0.15874 0.00908 0.98747 0 13.43772 0.28363 11.67571 0.24644 2.13309 0.11334 1.85329 0.09847
