Interactive editing

Interactive editing is possible on almost all graphical views of the data when msplot is created with the option EDIT=True. While the data is being displayed and edited, flag commands are saved in a file in your current directory. The flags are not actually applied to the data until you exit msplot. When you click on the Done button in msplot, you will be asked if you want to apply the flags or not: click on Yes if you want the flags applied.

To flag data, use the msplot control GUI to select all or a subset of the data (e.g. select all data for a single source, and plot amplitude versus time). In the plot window, draw boxes with the left mouse button to select regions, e.g.:
1) Move the cursor to a corner where you want to box emission;
2) Click on the left mouse button and hold it down while you
drag the mouse to the opposite side of the region;
3) Release the mouse button when you have the region the size you want it.
4) Hit the ``Escape'' key on your keyboard to remove a region.
Click on the Locate button to identify the antennas or time range of the selected data (results will be displayed in the logger window). Note that the listing may be very long if the region selected covers a large number of visibility points. Click on the Flag button to write flags to a file. Multiple flag regions may be selected before executing the Flag option.
