A look at the SINGS sample visibilities and the possible IRS slit orientations (updated 16 June 2003 for August 2003 launch)
For each galaxy, there is an optical image and table.
The yellow rectangles (table row 1) indicate each season's entire IRS observing window.
The red lines (table row 2) are the preferred windows.
Table row 3 indicates the preferred windows' PA range.
