Variables Panel
The Variables panel allows the user to view and edit the ISTP/IACG
variables defined within the file. Global attributes are used to
provide information about the data set as an entity. An understanding of
ISTP/IACG variables is required to use this panel. Refer to the following
sources for the definition and rules of use of ISTP/IACG variables:
-

-
ISTP/IACG Guidelines -- Variables (see
https://spdf.gsfc.nasa.gov/istp_guide/variables.html)
Variable List
All variables defined in the current CDF are listed by name in the upper
lefthand corner of the Variables panel. Selection
of a variable results in its definition being displayed on the rest of
the Variables panel.
