The other identifiers are radials that extend at the angle of the designated color. These six lines follow
the same displacement as the vector display. Note that since the PAL display is derived solely from
component information, there are not two phases for PAL signals. The +V phase is used (making the
vectors look similar to NTSC).
There is an alarm persistence of two seconds associated with any alarm indication. After an alarm has
cleared, two seconds will pass before the gamut alarm indicator returns to normal.
