AOT_SOURCES fields.
| Name | Type | Unit | Description |
|---|---|---|---|
| UID | str | n.a. | Unique ID that identifies the light source.(a,b) |
| TYPE | str | n.a. | Indicates the type of light source (either ‘Science Star’, ‘Natural Guide Star’, ‘Sodium Laser Guide Star’ or ‘Rayleigh Laser Guide Star’).(a) |
| RIGHT_ASCENSION | flt | deg | Right ascension (RA) of the light source at the start, epoch J2000 (equatorial coordinate system).(c) |
| DECLINATION | flt | deg | Declination (DEC) of the light source at the start, epoch J2000 (equatorial coordinate system).(c) |
| ELEVATION_OFFSET | flt | deg | Offset from the Main Telescope’s ELEVATION. |
| AZIMUTH_OFFSET | flt | deg | Offset from the Main Telescope’s AZIMUTH. |
| FWHM | flt | rad | Full width at half maximum of the light source, at zenith. |
Notes. (a)Strictly mandatory (value must not be null). (b)All entries in this field must be unique. (c)In non-sideral observations, right ascension and declination may change throughout the recording. The motion data for such sources is beyond the scope of this format and should be provided separately if relevant.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
