The SOFA type exposes the following members.
Methods| | Name | Description |
|---|
 | Af2a |
Convert degrees, arcminutes, arcseconds to radians.
|
| Anp |
Normalize angle into the range 0 <= a < 2pi.
|
| CelestialToIntermediate |
Transform ICRS star data, epoch J2000.0, to CIRS using the SOFA Atci13 function.
|
| CelestialToObserved |
ICRS RA,Dec to observed place using the SOFA Atco13 function.
|
| Dispose |
Cleans up the SOFA object
|
| Dtf2d |
Encode date and time fields into 2-part Julian Date (or in the case of UTC a quasi-JD form that includes special provision for leap seconds).
|
| Eo06a |

|
| IntermediateToObserved |
CIRS RA,Dec to observed place using the SOFA Atio13 funciton.
|
| Ir |
