File type specification:
The sga file extension is also used for a special Seismic Data Format - SEG Y. SEG "Y" is a format devised by the Society of Exploration Geophysicists (SEG), for transfer of demultiplexed seismic data on 9-track tape.
SEG Y was published in 1974, and superceded the SEG "Ex" format. SEG Y defines, for each tape reel, a 3200 byte EBCDIC text header, followed by a 400 byte binary header. The data follows as a variable number of traces. Each trace has a 240 byte header, followed by a variable number of samples, each represented as a 4-byte real value.
This sga file type entry was marked as obsolete and no longer supported file format.
This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.
