/* ** ** 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 58608.915100 0.000359 0.20592 0.01663 0.99194 0 20.36608 0.67371 15.37666 0.50849 4.19385 0.30890 3.16757 0.23324 58608.915786 0.000327 0.22362 0.01787 1.00000 0 20.27810 0.69215 15.72195 0.53665 4.53467 0.32771 3.51596 0.25407 58608.916515 0.000402 0.19161 0.01503 1.00000 0 19.30027 0.60983 14.98792 0.47358 3.69814 0.26546 2.87155 0.20612 58608.917238 0.000321 0.22366 0.01784 0.99099 0 20.71503 0.70522 16.06097 0.54676 4.63311 0.33427 3.59218 0.25919 58608.917884 0.000324 0.23139 0.01847 0.98214 0 20.03549 0.69191 15.59721 0.53863 4.63592 0.33362 3.61039 0.25983 58608.918604 0.000396 0.18862 0.01474 0.97810 0 20.33702 0.62919 15.79518 0.48867 3.83601 0.27536 2.97870 0.21381 58608.919380 0.000379 0.18995 0.01526 1.00000 0 20.16288 0.64214 15.74445 0.50143 3.82989 0.28238 2.99065 0.22051 58608.920109 0.000350 0.21256 0.01712 1.00000 0 19.57064 0.65948 15.21608 0.51272 4.15993 0.30421 3.23516 0.23661 58608.920838 0.000379 0.18963 0.01497 0.99237 0 20.67124 0.64772 16.04276 0.50267 3.91988 0.28401 3.04077 0.22031 58608.921573 0.000356 0.20368 0.01613 0.99187 0 20.46270 0.66709 15.89998 0.51837 4.16789 0.30076 3.23885 0.23369 58608.922293 0.000365 0.20922 0.01677 0.99206 0 19.26519 0.63881 15.03887 0.49873 4.03061 0.29404 3.14766 0.22960 58608.923054 0.000396 0.18697 0.01461 0.99270 0 19.99242 0.62482 15.77212 0.49294 3.73798 0.26764 2.94963 0.21118 58608.923862 0.000411 0.17858 0.01391 0.99296 0 20.16200 0.61526 15.76647 0.48114 3.60047 0.25806 2.81548 0.20178 58608.924623 0.000350 0.21561 0.01731 1.00000 0 19.36071 0.65626 15.15466 0.51364 4.17435 0.30376 3.26827 0.23776 58608.925329 0.000356 0.20446 0.01625 0.98374 0 20.37313 0.66503 15.97093 0.52132 4.16539 0.30180 3.26694 0.23670 58608.926035 0.000350 0.20391 0.01615 1.00000 0 20.43249 0.66820 16.01205 0.52364 4.16634 0.30063 3.26562 0.23563 58608.927068 0.000683 0.19004 0.01110 0.99576 0 20.97395 0.48656 16.46373 0.38193 3.98595 0.21356 3.12761 0.16755
