The large submillimetre map of rho Oph A in the ^12^C^18^O(3-2) line, obtained with the APEX 12m telescope, covers 10' in RA by 5' in DE, sampled on a rectangular grid, aligned with the equatorial coordinate system and with regular 20" spacings (548 spectra). An inner ^12^C^18^O(3-2) map, extending over 200" by 200" (462 spectra) is sampled at the Nyqvist frequency.
