This article is concerning the outbound WITS functionality of Survey curves.
There is an option in the Tool Settings on the Rig WITS tool that is checked by default - "Publish Survey MD/INC/AZM ONLY when surveys are saved"
When checked (by default) we WITS out survey data ONLY when a survey is saved. When a survey is saved we WITS out the survey data as it was entered.
When the box is unchecked we stream real-time survey information. NOT the actual saved survey info, but the info in real-time as it is sent up by the tool.
