# v23tosky-0.7.0¶

A sequence of 3D rotations.

#### Description

A sequence of 3D rotations around different axes. This represents JWST transform from the telescope coordinate system (V2,V3) to ICRS.

### Schema Definitions ¶

This node must validate against all of the following:

• This type is an object with the following properties:
• angles
 array Required
The angles of rotation in units of deg. The order of the angles is: [-V2_REF, V3_REF, -ROLL_REF, -DEC_REF, RA_REF]

No length restriction
Items in the array are restricted to the following types:
number
• axes_order
 string Required
A sequence of “x”, “y” or “z” characters representing an axis of rotation. The number of characters must equal the number of angles. For the JWST V23 to sky transform the axes are zyxyz.

No length restriction

### Examples ¶

JWST V2, V3 to sky transform.:

!<tag:stsci.edu:jwst_pipeline/v23tosky-0.7.0>
angles: [-0.0193, -0.1432, -0.04, -65.60, 273.089]
axes_order: zyxyz
