These may be useful in identifying data which deserve more detailed inspection. For example, by printing the PNG file, the user can determine whether an occultation was 'ingress' or 'egress' -- or whether there was an occultation at all. Certain data anomalies (saturation in the analog-to-digital converters, clipping in amplifiers ahead of the ADCs, receiver tuning errors, poor choices of receiver gain, etc.) can be readily seen in the plots. Each PNG file is sized to fit on a single 8-1/2 x 11 inch page. Each 'landscape' format page includes four panels showing a histogram of raw data (8-bit) samples (upper left), one-minute average power spectra derived from the raw samples (upper right), one-second averages of raw sample power versus time (lower left), and an extract of the first few lines of the source ODR PDS label (lower right). PNG file names have the form ydddhhmm_c.png where y is the one-digit year (1, 2, or 4) ddd is the three-digit day-of-year (001-366) hh is the two-digit hour (00-23) mm is the two-digit minute (00-59) c is the one digit receiver channel (1-4) The file names are chosen so that they match the ODR file names ydddhhmm.ODR. Receiver channels (c) are generally defined as follows. If the DSN station was DSS 42 or DSS 61, receiver 3 was X-band right circularly polarized (RCP) and receiver 4 was S-band RCP. For other stations receiver 1 was X-RCP, receiver 2 was S-RCP, receiver 3 was X-LCP, and receiver 4 was S-LCP. In 1994 only two channels (X-LCP and S-LCP) were often fed through two receivers, providing redundancy; the redundant plots are not included here. In most cases the plots are accurately described by text annotation within the panels. In a few instances the annotation was garbled or was hidden. In a few other cases, the annotation (which was composed automatically by the plotting program) may simply be wrong. Users should exercise care in using the plot information; it is provided to assist browsers but has not been rigorously produced. Each panel was generated by MATLAB as a Level 1 PostScript file for black and white printers. The panels were then assembled into single page PostScript files using the psmulti utility, a PERL script written by D. Murray Laing. The computing platform was a Sun SPARC-2 running SunOS 4.1.3.

The PostScript files have been converted to PNG during PDS4 migration for long-term preservation compliance. collection_browse_inventory.csv 2026-06-01T08:35:00 12712 ddbbf4dec2161115285caf67e5f0120a 0 PDS DSV 1 227 Carriage-Return Line-Feed Comma 2 0 Member Status 1 ASCII_String 1 P indicates Primary member, S indicates Secondary member.
