Possible “operation points”, i. e. combination of class, resolution, scan mode and frame rate, are not part of this documentation and can be taken from the original Panasonic AVC-ULTRA product overview here. A copy of the document is provided here: AVC-ULTRAoverview.pdf

MXF Operational Pattern

In the original AVC-ULTRA specification, OPatom is defined for AVC-Intra and Op1b for AVC-LongG. Currently, only Op1a is supported for all AVC-Ultra formats. Additionally, Op1b is supported for AVC-LongG. In this case you have to define the muxing mode as follows:
