While the order of the elements of the line is important, the parsing subroutines will omit leading and trailing spaces and tabs from each element, so they may be positioned for clarity. All of the IRAS map projections are included so objects can be plotted against contoured IR sky flux. The map may be labeled using terminal or computer-generated characters. Computer drawn characters use the Hershey font set and are, in decreasing detail, Complex, Italic, Duplex, and Simplex. The font size may be set separately for headings, tickmark labels, axis labels, time tag, plate scale, and magnitude scale table.
Font type is the same for heading, tick, and axis labels.
Portions of the displayed map may be enlarged using the Zoom menu or cursor command. The original display parameters are remembered and may be recovered using the Unzoom commands. If the default automatic grid spacing has been specified, an optimum spacing is program-selected when zooming. If plotting to a specific plate scale, the size of a zoomed map can be specified by plate scale. By zooming, portions of images can be selected in sky coordinates rather than in rows and columns.
