/* ** ** 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 58508.909942 0.000379 0.15436 0.01210 1.00000 0 23.77466 0.67431 19.36278 0.54900 3.66982 0.26814 2.98883 0.21851 58508.910726 0.000405 0.14801 0.01149 0.99286 0 22.93260 0.63747 19.21235 0.53406 3.39433 0.24598 2.84436 0.20601 58508.911528 0.000396 0.14991 0.01163 0.98540 0 23.17833 0.64345 19.53995 0.54246 3.47456 0.25166 2.92864 0.21212 58508.912291 0.000367 0.16337 0.01299 1.00000 0 22.25898 0.65448 18.79840 0.55271 3.63653 0.26870 3.06998 0.22685 58508.913084 0.000425 0.13191 0.01018 0.97959 0 24.50377 0.63788 20.71626 0.53928 3.23228 0.23473 2.73169 0.19837 58508.913892 0.000382 0.14408 0.01126 1.00000 0 24.32696 0.66979 20.59024 0.56692 3.50510 0.25626 2.96619 0.21685 58508.914722 0.000448 0.12998 0.00991 0.99355 0 23.72428 0.61024 19.93009 0.51264 3.08357 0.22130 2.59218 0.18603 58508.915564 0.000394 0.14664 0.01138 0.99265 0 23.75484 0.65262 19.86579 0.54577 3.48331 0.25293 2.91380 0.21160 58508.916313 0.000356 0.16581 0.01292 1.00000 0 23.33051 0.68929 19.37274 0.57229 3.86849 0.27901 3.21292 0.23177 58508.917025 0.000356 0.16512 0.01314 1.00000 0 22.95831 0.67889 19.20127 0.56776 3.79095 0.28018 3.16982 0.23423 58508.917760 0.000379 0.16538 0.01273 0.99237 0 22.18848 0.64506 18.65283 0.54228 3.66955 0.26162 3.08478 0.21992 58508.918568 0.000428 0.13519 0.01066 1.00000 0 23.14048 0.62215 19.40814 0.52179 3.12832 0.23185 2.62084 0.19419 58508.919363 0.000367 0.15993 0.01248 1.00000 0 23.04299 0.66728 19.47180 0.56388 3.68522 0.26692 3.11312 0.22548 58508.920113 0.000382 0.16035 0.01238 0.97727 0 22.95476 0.66018 19.18291 0.55169 3.68088 0.26376 3.07764 0.22053 58508.921013 0.000518 0.14201 0.00998 0.98883 0 23.28978 0.56587 19.50478 0.47392 3.30736 0.21802 2.77067 0.18267
