	short get ();
	void set (short value);
}

Return Value

GAIN VALUE MODE: The current gain value.

OR

This is an optional property and can throw a PropertyNotImplementedException if Gain is not supported by the camera.

• GAIN VALUE MODE - The Gain property is a direct numeric representation of the camera's gain.
  • In this mode the GainMin and GainMax properties must return integers specifying the valid range for Gain
  • The Gains property must return a PropertyNotImplementedException.
• GAINS INDEX MODE - The Gain property is the selected gain's index within the Gains array of textual gain descriptions.
  • In this mode the Gains method returns a 0-based array of strings, which describe available gain settings e.g. "ISO 200", "ISO 1600"
  • GainMin and GainMax must throw PropertyNotImplementedExceptions.
  • Please note that the Gains array is zero based.

A driver can support none, one or both gain modes depending on the camera's capabilities. However, only one mode can be active at any one moment because both modes share the Gain property to return the gain value. Client applications can determine which mode is operational by reading the GainMin, GainMax and Gain properties. If a property can be read then its associated mode is active, if it throws a PropertyNotImplementedException then the mode is not active.

If a driver supports both modes the astronomer must be able to select the required mode through the driver Setup dialogue.

During driver initialisation the driver must set Gain to a valid value.

Please note that ReadoutMode may in some cases affect the gain of the camera; if so, the driver must be ensure that the two properties do not conflict if both are used.

This is only available in Camera Interface Version 2 and later.
