FITS (Flexible Image Transport System) format is defined in 'Astronomy and Astrophysics', volume 376, page 359; bibcode: 2001A&A...376..359H The RX start time is a reasonable approximation to the experiment mid-time. A more accurate mid-time is DATE-OBS + (EXPTIME-RTT)/2 which is typically about 3s earlier Additional -6.45466400328587e-08 s added: Range curvature correction If FREQSAMP < FFTLEN, then the transform was zero-filled SAMPPBD is the number of input samples taken per baud. ROWSPBD is the number of output image rows saved per baud. ROWSPBD and SAMPPBD may differ either because data were thrown away, or because the extra samples were used in the frequency processing. CODEPROC is the code processing method: values are short, long_orig, or long_mod. short means short-code data processed so that each Doppler fft includes data from all samples per baud; long_mod means long-code data processed in the same way; long_orig means long-code data where each sample per baud is processed separately and the separate images are then interleaved in delay.
