GUI: wrong instrumental ranges for setting angles and depth

Current ranges for manual setting beam and detector angles are wrong.

GISAS:

Was:

• detector \alpha in [-max_double, max_double]
• detector \phi in [-max_double, max_double]

Expected:

• detector \alpha in [-90, 90]
• detector \phi in [-90, 90]

Off-Specular:

Was:

• beam inclination angles [0, max_double]
• detector \alpha in [-max_double, max_double]
• detector \phi in [-max_double, max_double]

Expected:

• beam inclination angles [0, 90] (or [-90,90] ???)
• detector \alpha in [-90, 90]
• detector \phi in [-90, 90] <------------ why do we have this at all?

Specular:

Was:

• beam inclination angles [-max_double, max_double]

Expected:

• beam inclination angles [0, 90]

DepthProbe:

Was:

• beam inclination angles [-max_double, max_double]
• depth [0, max_double]

Expected:

• beam inclination angles [0, 90]
• depth [-max_double, max_double]
