Output Files

Although Extract is really an ANALYSIS thorn, at the moment it is scheduled at POSTSTEP, with the iterations at which output is performed determined by the parameter itout. Output files from Extract are always placed in the main output directory defined by CactusBase/IOUtil.

Output files are generated for each detector (2-sphere) used, and these detectors are identified in the name of each output file by R1, R2, ....

The extension denotes whether coordinate time (tl) or proper time (ul) is used for the first column.

• rsch_R?.[tu]l

  The extracted areal radius on each 2-sphere.

• mass_R?.[tu]l

  Mass estimate calculated from $g_{rr}$ on each 2-sphere.

• Qeven_R?_??.[tu]l

  The even parity gauge invariate variable (waveform) on each 2-sphere. This is a complex quantity, the 2nd column is the real part, and the third column the imaginary part.

• Qodd_R?_??.[tu]l

  The odd parity gauge invariate variable (waveform) on each 2-sphere. This is a complex quantity, the 2nd column is the real part, and the third column the imaginary part.

• ADMmass_R?.[tu]l

  Estimate of ADM mass enclosed within each 2-sphere. (To produce this set doADMmass = ``yes'').

• momentum_[xyz]_R?.[tu]l

  Estimate of momentum at each 2-sphere. (To produce this set do_momentum = ``yes'').

• spin_[xyz]_R?.[tu]l

  Estimate of momentum at each 2-sphere. (To produce this set do_spin = ``yes'').
