/* ** ** 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 59340.226852 0.000671 0.14307 0.01105 0.98276 0 14.21126 0.38430 12.08415 0.32678 2.03323 0.14710 1.72632 0.12490 59340.228215 0.000692 0.14481 0.01110 0.97490 0 13.95141 0.37601 11.85179 0.31939 2.02028 0.14504 1.71507 0.12313 59340.229598 0.000692 0.14399 0.01105 0.98745 0 13.60489 0.36880 11.65569 0.31596 1.95899 0.14065 1.67778 0.12046 59340.230926 0.000631 0.16057 0.01223 0.98624 0 13.51304 0.38270 11.61034 0.32881 2.16975 0.15343 1.86357 0.13177 59340.232231 0.000674 0.15567 0.01218 0.97854 0 12.90016 0.36585 11.02943 0.31278 2.00822 0.14643 1.71599 0.12512 59340.233680 0.000775 0.13140 0.01011 0.97761 0 13.39698 0.34952 11.41907 0.29787 1.76043 0.12736 1.50230 0.10869 59340.235610 0.001155 0.15074 0.00887 0.97995 0 13.53202 0.28760 11.46767 0.24372 2.03983 0.11196 1.72908 0.09490
