Name: PGPAP Purpose: change the size of the view surface Category: GRAPHICS File: pgplot.src Author: T.J. Pearson Use: see description below. Description: SUBROUTINE PGPAP (WIDTH, ASPECT) REAL WIDTH, ASPECT This routine changes the size of the view surface ("paper size") to a specified width and aspect ratio (height/width), in so far as this is possible on the specific device. ... The new size applies to all subsequent images until the next call to PGPAP. ...

... If the measuring aperture varies, a varying amount of starlight will be excluded. Furthermore, the excluded fraction is wavelength-dependent; so the transformation from instrumental to standard system changes. ... Unfortunately, sometimes it is necessary to combine measurements made with different field stops. Observers should realize that this really means different instruments; the differences are usually several per cent. ... Usually, the actual aperture sizes are only approximately known. ...

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. ...
