The vector magnetograph is no longer in use.
The image displayed is an example of a MSFC vector magnetograph data product.
The vector plot consists of an overlay on the visible-light image (gray-scale)
of the line-of-sight component of the field (contours) and the travsverse
component of the field (ticks).
