AOT_TELESCOPES fields.
| Name | Type | Unit | Description |
|---|---|---|---|
| UID | str | n.a. | Unique ID that identifies the telescope.(a,b) |
| TYPE | str | n.a. | Indicates the type of telescope (either ‘Main Telescope’ or ‘Laser Launch Telescope’).(a) |
| LATITUDE | flt | deg | Latitude of the telescope (World Geodetic System). |
| LONGITUDE | flt | deg | Longitude of the telescope (World Geodetic System). |
| ELEVATION | flt | deg | Elevation of the telescope at the start, the angle between the object and the observer’s local horizon with 0° being the horizon and 90° being zenith (horizontal coordinate system). |
| AZIMUTH | flt | deg | Azimuth of the telescope at the start, the angle of the object around the horizon with 0° being north, increasing eastward (horizontal coordinate system). |
| PARALLACTIC | flt | deg | Parallactic angle at the start, the spherical angle between the hour circle and the great circle through a celestial object and the zenith. |
| PUPIL_MASK | str | n.a. | Image-reference. |
| PUPIL_ANGLE | flt | rad | Clockwise rotation of the pupil mask. |
| ENCLOSING_D | flt | m | Diameter of the smallest circle that contains the entirety of the pupil (enclosing circle). |
| INSCRIBED_D | flt | m | Diameter of the largest circle that can be contained in the pupil (inscribed circle). On monolithic circular pupils this is equivalent to ENCLOSING_D. |
| OBSTRUCTION_D | flt | m | Diameter of the smallest circle that contains the entire central obstruction. |
| SEGMENTS_TYPE | str | n.a. | Describes the type of the segments that constitute the pupil. Value must be ‘Monolithic’ if the pupil is monolithic, ‘Hexagon’ if the segments are hexagons or ‘Circle’ if the segments are circles.(a) |
| SEGMENTS_SIZE | flt | m | Size of the segments that constitute the pupil, measured as the diameter of the smallest circle that contains the entirety of a segment. If no segments exist (monolithic) this must be null. |
| SEGMENTS_X | lst | m | List of horizontal coordinates of each segment in the pupil.(c) |
| SEGMENTS_Y | lst | m | List of vertical coordinates of each segment in the pupil.(c) |
| TRANSFORMATION_MATRIX | str | n.a. | Image-reference. |
| ABERRATION_UID | str | n.a. | AOT_ABERRATIONS row-reference. |
