Requirements

Requirements are used to modify elements of an observation specification or other scheduling element. A Requirement may modify the overall timing or pointing for that element (and all lower-level elements it is composed of), or may provide specific settings to be applied to the component exposures (e.g., the  LAMP STATE under CALIBRATION ).

The various special requirements are listed in separate articles within RAUG:

• Special Requirements
• Linking Requirements
• Calibration Requirements
• Engineering Requirements

The Table of APT Requirements provides links containing further information on specific special requirements.
