For observations of comets to be of scientific value the observer should concentrate on the following: estimates of the total visual magnitude of the comet, the diameter of the coma, the degree of condensation, estimates of the length and position angle
of the tail, and detailed visual descriptions, sketches and photographs.

Caption: Comets are rendered to show the position angle
of a predicted tail based on the object's position from the Sun and Earth at the time of observation.
[PHI] is the angle between U and horizontal axis which determined by blade position angle
Stability of the mechanism was achieved at the position angle
The inner ring moves both vertically and horizontally at a given step in a certain range, and the position relation (contact, separation, interference) between the inner raceway and each roller at the bottom of the bearing is obtained in different positions, and the number and position angle
of rollers which contact with the inner raceway are obtained.
Figure 9(b) shows the PSG screen captured with the head and body position angle
Pole figure is scanned by measuring at a fixed 2th position angle
(crystal orientation), a complete scan (spins the sample about its normal) can be performed at each specific tilt angle (Ps).Pole figure measurement is considered as an important process needs to be undertaken to get a successful characterization of the sample .
Driving position Angle
your seat backwards a little so it supports your spine, and position the seat so that you can reach the hand and foot controls easily.
The angle formed by the line connecting the center of mass (CM) with the middle of the grasping hand and the vertical (z) axis of the coordinate system defined body position angle
during longswings (Yeadon and Hiley, 2000).
