Dictionary:Depth sampling interval

{{#category_index:D|depth sampling interval}} 1. The interval $\Delta z$ for sampling a sonic log to make a synthetic seismogram. Generally

$\Delta z\leq V_{min}\Delta t/2$,

where $V_{min}$=minimum velocity and $\Delta t$=time sampling interval.

2. Time sampling interval (q.v.) except after conversion from time to depth.

3. In depth migration, the interval for sample outputs.
