Some changes or distortion in the tail and its position angle may arise from the
comet's velocity around the sun as well as from solar activity, as evidenced in the
solar wind. Measurements of position angle are quite simple to determine if you ...

the direction vector d onto e2 and CT, we obtain the following expressions for
determining the position angle is: cos & = £3 . d = ((-.vzk/,- + (-vzK/v + (.v2 + \2)d-)/
(rQ) (7.4) sin i? = e2-</ = ((-y)c/.x + (x)dy)/Q . The PosAng function utilizes these ...

59 The position-angle of the bright limb Figure 28 shows the appearance of a
planet whose phase is about F = 0.7. The dashed outline is of that part of the disc
which is invisible, and the line NS is the projection of the Earth's axis onto the
disc.
Peter Duffett-Smith, 1988

Observing and Measuring Visual Double Stars
The computational benefit of these alternative expressions, apart from avoiding
any division by zero, is that the required trigonometric functions, x and y, have
been evaluated at the outset and are used in calculating both the position angle
and ...

The other is their position angle, the position in the telescopic field of the
secondary star relative to the primary (the brighter). Estimation of a position angle
lends itself more easily to simple, visual methods than does the measurement of

it is also of interest to study the position angle of linear polarisation V = 5tan-1(£//
Q) as a function of pulse phase. Normally the position angle of the linearly
polarised flux varies throughout the pulse in a smooth and regular manner that is

Explanatory Supplement to the Astronomical Almanac
The quantities shown are: e, the sub-Earth point; s, the subsolar point; ds the
apparent distance from the sub-Earth point to the subsolar point; PAS the position
angle of the subsolar point; n, the north pole of the planet; d„ the apparent
distance ...

The position angle assumed in the model is 170◦, shown by the solid line. The 5◦
wedges with the extreme velocity for each annulus is marked. It can be seen that
streaming shifts the estimated position angle from the true position angle.

These isophotes are in general relatively uniform ellipses, whose ellipticity can
be determined; the position angle in the sky is defined by the orientation of the
major axis of the ellipse (the position angle is defined with respect to north and is
