Crop Samples
This operator crops samples from each input ping that are outside of specified boundaries. The boundaries can be expressed by sample number, range or depth. Entire samples are excluded based on their midpoint; the remaining data is not resampled or padded with no-data values.
This operator does not perform any interpolation or averaging—it simply excludes out-of-range samples while leaving the remaining data unchanged. This lightweight cropping method offers improved clarity and performance for workflows where you only want to discard irrelevant samples rather than regrid or resample data. Cropping is based on the sample midpoint and supports heaved data. No-data padding is not used.
