OutputFlags
OutputFlags()Per-output rejection status flags.
These bits apply to spatial-shaped output_flags arrays, not to the stack-shaped sample_flags diagnostic arrays.
Notes
Values are PREMASKED=1, MAXITERS=2, NKEEP=4, MAXREJ=8, and GROW=16. Multiple conditions are combined by bitwise OR. Zero means normal completion and does not imply that no samples were rejected. Use sample_flags to inspect individual sample causes.
