21. The digital method frequently called " Fraser correction " starts from the Franklin approximation for the tilt angle ?. 22. This is a self-contained system that uses three ring laser gyros to determine azimuth, elevation angle and trunnion tilt angle . 23. Important specifications to consider when searching for tilt sensors and inclinometers are the tilt angle range and number of axes. 24. At a small tilt angle , the lift is greater for flat fish than it is for fish with narrow bodies. 25. They set the maximum tilt angle at 9 degrees, which could be added to any cant in the underlying railbed. 26. It is able to climb a gradiant of 80 degrees and travel through grounds with a tilt angle of 25 degrees. 27. Magnetic actuators offer very good linearity of the tilt angle versus the applied signal amplitude, both in static and dynamic operation. 28. As the sample is tilted during imaging, the electron beam interacts with a relatively greater cross-sectional area at higher tilt angles . 29. In contrast, a tilt angle of 17?between the Cp * rings is observed in the crystal structure of the SbF 6-salt. 30. A cylindrical hole would quickly block light passing through the flat from the primary mirror as the steering flat tilt angle increases.
