Angle parameters are intended for right ascensions and declinations, where conversion from hours/minutes/seconds or degrees/minutes/seconds may be needed. For other angles, such as small offset angles, a real parameter is more appropriate. Note that the maximum range of the angle type is [-360,360] degrees.
The angle can be entered in one of the following formats:
(+|-)xxdxxmxx[.xxx]s (degrees, minutes and seconds) xxhxxmxx[.xxx]s (hours, minutes and seconds) [(+|-)]xxx[.xxx] (decimal degrees)
where `x' is a single digit, `d',`m',`s' and `h` are literal characters
and square brackets denote optional items. The number of digits shown
is not significant.
Note: Angle parameters are accessed by the task as a real value, in degrees.
