No pixel averaging; thus vertical (declination) scale is 0.35 arcsec per pixel while horizontal (RA) scale is 0.8 arcsec per pixel. SEEING 1.5 arcseconds " NOTE = " The following erratum was noted by Mikael Aronsson for this file: According to the COMMENT section of the FITS header, the UT range was 12:37 to 12:50, which implies that the mid-time was 23:43.5 (= 20.530/4/86), which in turn indicates that the TIME-OBS value [OBSERVATION_TIME in the PDS label] given is incorrect.
