IMAGE source: No checking of SourceRA and DEC needed #33

Closed hamogu closed 9 months ago

hamogu commented 5 years ago

Using the IMAGE source, I get:

Source rays will not hit the telescope.
marx: Error creating source.

if SourceRA and SourceDEC are outside the FOV. However, for IMAGE sources that check is irrelevant, because the IMAGE is always assumed to be centred on the line-of-sight, so that check should just be skipped in this case. It's confusing to users because it implies that SourceRA and DEC are used in some way when they are not.

Seen again by a different user today. So, it seems that people run into this and I should probably fix it.
