The default extension for the name of a field file is .em.
[header] { [rest field] } <end>
The type of the file must be field.
{ <environment> $int$:32 } [transmitter] [receiver] [field values]
The environment value represents the check sum of the environment file for which the field file has been computed.

The indices correspond to the list of receivers and transmitters. The complex field is given for the receiving point according to the coordinate system of the last incoming ray whose angles theta and phi are given as the first pair of values after the delay. The second pair gives the angles of the first ray existing the transmitter antenna. Multiplying the delay with the speed of light computes the length of the ray path.
