There is also a full set of binary orbital parameters that can be fitted as well as exponentials. Note that although three exponentials are available only two can be fitted. Therefore the command swap exponential will swap the parameters of the given exponential with the parameters of the third exponential. In a similar manner with binary parameters, although three sets of binary parameters are available only one can be fiited, hence swap binary will swap the required set with the first set. Restore all Bats will remove the delete flag from all bats.
Return returns to the cursor screen.
Change parameters will show a new screen where the parameters can be altered. The square boxes are check boxes and are set on for required operation, i.e. those quantities to be used in a fit. The round circles are radio controls and only one in a particular area can be on at any one time, in general these define what the action is when the left hand mouse button is pressed. The epoch can be set at any point on the plot, this in fact does an update epoch to that date, or the button Centre can be pressed when the epoch will be set midway between the first and last data points on the screen. Bat id gives details of the nearest point to the cursor, this can be done at any time with the middle mouse button.
