Plot variables and their indices

Some data selection widgets for plotting display more indices than needed for some of the plot variables in order to avoid recycling of the data selection widget if the variables change. In the following tables, an overview is presented over the indices applicable to the plot variables. They are organized by class, even though, strictly speaking, an $\cal OYST\!ER\,$ plot class refers only to a specific selection of variables listed in a plot selection widget. More precisely, the integration interval (if applicable) is the same for all variables for a table.

Also note that the IDL variables in italic font denote a derivation from this variable, i.e. the data is not exactly identical to the variable contents. Where the IDL variable field is left blank, the formula is more complicated and might involve more than one variable.
