Allows you to specify a drift scan: motion at a constant velocity along a great circle. ... The path starts at the new object position (though the telescope actually intersects the path later, see Subtleties ). ... Note that the units are always /sec for both axes. ... The velocity along the path is 0.01 /sec. ... The path is assumed to start when you hit the Slew button (more precisely, when the TCC parses the command). However, it takes the telescope awhile to slew to meet the specified path. ...

. F IGURE . 3. Relations between the metallicity and other GC parameters. The open triangles are thick-disk clusters; open circles, old halo clusters; filled circles, young-halo clusters; filled triangles, corona clusters; and crosses, metal-poor clusters with unknown (B–R)/(B+V+R) . Only clusters with R<60 kpc are shown in (c). A sharp jump near [Fe/H]=-1.0 is seen in all plots. discussion in the text | previous figure | next figure .

The images shown above are based on tiling of the hyperbolic plane with equilateral triangles having angles not of 60 o but rather 360/7 degrees, so 7 such triangles fit around a point. The image on the left shows the triangles and circles drawn from the vertices that each touch 7 other points. On the right, the pattern formed by these circles has been filled with blue and gold. ...

... This is not a great circle arc. For small angles the error is not significant. ... Top: great circle offset - .17 degrees (10 amin). ... Middle: great circle offset = .5 degree= 30 arcmin. The error at 3.5 deg za is1-2 asecs. bottom: great circle offset=3 degrees (what green bank used). The error at 3.5 deg za is about 3 amin. If we keep the offset to +/- 20 amin and za > 3.5 degrees then we shouldn't have any problem with the position error. processing: x101/100407/byurot.pro . ...
