Datacolor Spyder3 Elite Help Manual page 24

A Target can specify just a Tone Response (e.g. Gamma) and a White Point or it
can also include Black and White Luminance values that are used in Measured
Luminance mode. It can also determine if the monitor will be treated as
SpyderCertified
The easiest way to create a Target is to proceed completely through a calibration
process, setting all of the Target values and then after Calibration is complete,
choose Save Target As from the File menu to create a Target that records all of the
values used for that Calibration. That Target will then be available in the Target:
popup to use for future calibrations or other monitors.
