Voyager Mercury features     The default Mercury uses a texture underlay grid grd=1 showing surface features from Mariner 10 imaging, flybys on:

29 Mar 1974 (to within 272 km)
21 Sep 1974 (to within 48000 km)
16 Mar 1975 (to within 327 km)

The texture underlay grids available under [Features:] of Voyager: Mercury are:

[Mariner 10]

grd = 1

Mariner 10 flyby shaded relief greytone composite image (from map USGS I-1149, 1979; 0.03125° resolution)

from research of Dr. Tony Cook, National Air and Space Museum (NASM), to obtain topographic stereo imagery of Mercury surface from Mariner 10 imagery:

[NASM resolution map]		grd = 2		best image resolution map (0.125° resolution)
[NASM min. phase angle]		grd = 3		minimum phase angle map (0.125° resolution)
[NASM max. phase angle]		grd = 4		maximum phase angle map (0.125° resolution)
[NASM mult. phase angle]		grd = 5		multiple phase angle map (0.125° resolution)

The standard image overlays available under [Features:] for optional longitude and latitude marking or distance scale bars are explained Advanced Help: generic options.

Note: Any grd, gmt, geo, lbl, vel, mon, msc, or opt code might change in the future, so be sure to check here for the current values!
