This file contains additional information such as Exif metadata which may have been added by the digital camera, scanner, or software program used to create or digitize it. If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file. The timestamp is only as accurate as the clock in the camera, and it may be completely wrong.

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 -2.20928853877922e-07 s added: Range curvature correction Closed-loop time estimated from baud 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.
