WCS turn around #2

Open maray opened 9 years ago

The WCS pix2world conversion on astropy CORRECTLY turn around the clock when you arrive to a zero limit. For example, if the object is in alpha=0.0 center, then all the pixels to the right will be like delta_something, while pixels to the left will be 365 - delta_something, rather than simply the negative number. This is a complex issue that we must address here!

If I remember correctly this affect the synthetic module.
