Source_Signature CTag

When loading field data to the NDR, one of the requirements is to load the source signature from the survey.

The Form and Manner document states:

It states that the format can be in TXT (ASCII) or PDF format.

Below are some examples of what could be considered to conform to a Source_Signature CTag:

An ASCII or binary file that has a time series of the predicted source, this may be from a modelling software or from a far-field hydrophone.

A report containing clear graphs of the source signature time series.

A report containing source airgun type, pressure, layout details, sizes, depths and which are spares in an array. There should be enough detail to allow modelling of a source signature from the details in the report.

A report or ASCII file detailing the source signature being recorded in Seg-D or Seg-Y channels, for example near field hydrophones and which channels they are in.
