The SIG file is a binary file. It holds signal strength as calculated by a cartesian coverage and is assosiated with a picture file.
The location of the file is not mandatory as long as it is in the same folder with the raster image file that it is associated with.
|Integer here in VB is equivalent to a signed SHORT in C Single here in VB is equivalent to a FLOAT in C|

|System||the system gain As Single|
|Fac||the correction to get the dBµV/m As Single|
|Freq||the frequency in MHz As Single|
|Trh||the receiver threshold in dBm As Single|
|Tr1||the minimum value of the signal to draw As Single|
|Sx and Sy||the data matrix size As Integer|
