SlewInitialState¶
This table contains all of the initial state information from a given visit’s slew. The state information is collected before the slew to the given target has started. The SlewHistory_slewCount column points to a given slew in the SlewHistory table.
| Column | Description |
|---|---|
| slewStateId | Numeric identifier for a particular slew state. |
| Session_sessionId | The simulation run session Id. |
| slewStateDate | The UTC date/time of the slew state information (units=seconds) |
| targetRA | Current target Right Ascension (units=degrees). |
| targetDec | Current target Declination (units=degrees). |
| tracking | Whether or not the telescope is tracking the sky. |
| altitude | Current target altitude (units=degrees). |
| azimuth | Current target azimuth (units=degrees) |
| paraAngle | Current parallactic angle of the rotator (units=degrees). |
| domeAlt | Current dome altitude (units=degrees). |
| domeAz | Current dome azimuth (units=degrees). |
| telAlt | Current telescope altitude (units=degrees). |
| telAz | Current telescope azimuth (units=degrees). |
| rotTelPos | Current position of the telescope rotator (units=degrees). |
| rotSkyPos | Current position of the camera on the sky (units=degrees). |
| filter | Band filter for the recorded slew state. |
| SlewHistory_slewCount | Numeric identifier that relates to an entry in the SlewHistory table. |
