... Alfa_ang is a GUI for the rotang routine. The purpose of this routine is to calculate the optimum rotation angle for ALFA given the RA and Dec of a source and the date and time of the observation. The routine also returns the azimuth and zenith angle of the telescope at the requested time, thus it can be used to find the correct rotation angle and azimuth for the Fixed Azimuth Drift Scan observing mode used by the AGES drift precursor observation. ... To run alfa_ang at Arecibo: . ...

... Analysis of the WFPC2 saturated star images indicate that the large angle scattering (>3" from a star) is significantly higher than expected. ... The first set was from the SMOV Ghost Check proposal 5615, in which 100 second images of d Cas (V=2.7) were obtained at the center of each chip in F502N. The second set was a series of 6 second exposures of Vega (V=0.0) centered on WF2 through F410M (WFPC2 GTO proposal 5205). ... The source of the WFPC2 scattering may be the CCDs. ...

In addition, they are invariably tilted at an angle around 45 , to make sure that the arrival of the sun's rays is as close to perpendicular as possible. ... The rays of the summer sun, high in the sky, arrive at a steep angle and heat the land much more than those of the winter sun, which hit at a shallow angle. ...

Deriving the sine or cosine of an arbitrary angle takes a bit more math than is covered here. ... Note first of all that a right-angled triangle contains two angles. ... Because the side opposite to A is the one adjacent to (90њ- A), it follows that the sine of one angle is the cosine of the other, and vice versa: . ... Consider the triangle PQR (drawing) with all three angles equal to 60њ. ... If we want the angle A to grow in equal steps of 15 o , we still need the sine and cosine of 15њ and 75њ. ...

Next: Identification loop Up: Wavelength Calibration Previous: The Echelle Relation . As a consequence of the cross-disperser dispersion relation, a given line repeated in two overlapped regions of the spectrum must be found at the same y position if spectrum and detector are perfectly aligned. ... The above condition provides a geometrical way to estimate the angle, as: , with the difference in y position of the two occurences of the pairs and the difference of their x positions. ...

... We can help students grasp the significance of Hubble's extremely keen eye, and learn a bit about angles and math in the process, with the following in-class activity. ... Looking through binoculars or telescopes allows us to magnify a small section of the sky. To measure sizes or distances in that small section, astronomers divide a degree into 60 smaller pieces called arcminutes, and further subdivide minutes into 60 smaller sections called arcseconds. ... 30 feet = . ... 36 seconds . ...
