Geometrical distribution for non-impulsive sources

A method to manufacture a geophysical data product, the method comprising:

• receiving a proposed geometrical distribution for a first non-impulsive source and a second non-impulsive source of a source array;
• performing a near-field-to-notional computation to yield a computed notional output of the first non-impulsive source and a computed notional output of the second non-impulsive source;
• determining, whether the computed notional output of the first non-impulsive source has a first amount of residue, from the second non-impulsive source and relative to an amount of energy of the first non-impulsive source at the operating frequency band of the first non-impulsive source, greater than a threshold amount of residue;
• determining whether the computed notional output of the second non-impulsive source has a second amount of residue, from the first non-impulsive source and relative to an amount of energy of the second non-impulsive source at the operating frequency band of the second non-impulsive source, greater than the threshold amount of residue and
• providing an indication whether either of the first or second amounts of residue is less than or equal to the threshold amount of residue;
• and
• responsive to providing an indication that the first and second amounts of residue are less than or equal to the threshold amount of residue:
• obtaining geophysical data using the source array;
• and
• recording the geophysical data on one or more non-transitory machine-readable media, thereby creating the geophysical data product.
