Start at (azimuth) line 1, (range) pixel 1 (near range). Data is written line by line (major row order). We give the binary data a .raw extension.
The complex interferogram is written pixel interleaved (see D.2). Each complex pixel is written as 4 byte real, 4B imaginary part.
|1st pixel||2nd pixel||...||pixel P|
After unwrapping of the phase the result can no longer be stored as a complex value, because a complex number only can distinguish between phase values in the principal interval . Therefor a new format is used/will be used. Either the unwrapped phase is simply stored in a 4B float file, similar to table D.2 without the imaginary part (as are other files, like the phi, lambda, and height matrices after geocoding), or a hgt file is generated (see table D.3.

Computations are done in general in the original master system. (no matter if cut-out or multilooked.)
Time system (orbit) is in seconds of day. Ephemerides orbit system is more or less WGS84.
A matrix is starts at 0,0 etc.
Offset for a certain point is defined as: coordinate in slave system = coordinate in mastr system + offsets.
