The earliest altazimuth instruments consisted of a base graduated with a full circle at the limb and a vertical angle measuring device, most often a semicircle.
32.
The ride navigates through and around buildings with many airtime moments, culminating in a Grand Spike that sends riders to a record-breaking, near-vertical angle of 87 degrees.
33.
By measuring the same horizontal and vertical angles in these two modes and then averaging the results, centering and collimating errors in the instrument can be eliminated.
34.
From the external reference position O, the direct distance to L 1 is measured to P 1 along with the vertical angle V1 and azimuth A 1.
35.
This modification added a set of vertical antennas and a new elevation-measuring CRT to read them, along with a radiogoniometer that allowed the vertical angle to be accurately measured.
36.
Instead the person instinctively applies quick " fuzzy " estimates, based upon previous experience, to determine what output values of force, direction and vertical angle to use to make the toss.
37.
The harvest season extends from mid-August, when the fields are heavy with champagne and sauvignon blanc, to late October, when the late-ripening cabernet grapes crisscross the hills at improbable vertical angles.
38.
Then the output of this system is represented by a horizontal angle and a vertical angle of the sound sources which is found by the peak in the combined 3D spatial spectrum.
39.
There are " L " and " T " adapters for rigid track, as well as flexible ones for unusual angles, or to change the vertical angle where a ceiling changes slope.
40.
The 5 / 16 inch ( a standard recommendation in the early twentieth century ) web plates are fastened with 8 rivets to the 100 x 75 x 9.5 mm vertical angles.
