2. Spatial Region Boundaries
Describes how spatial region boundaries are handled. The golden rule for spatial region filtering was first enunciated by Leon VanSpeybroeck in 1986: . ... With this in mind, the rules for determining whether a boundary image pixel or table row are assigned to a region are defined below. For image filtering, pixels whose center is inside the boundary are included. ... That is, an row is inside the boundary without regard to its integerized pixel value. ...

... The coronographic spot imaged onto the focal plane provides a circular occulted region 0.3 arcsec in radius. ... Coronographic imaging requires an acquisition sequence at the beginning of the observation to center the target onto the occulting spot since the size of the occulting spot is smaller than typical HST blind-pointing errors. ... The acquisition software, analyzes this aperture, locates the center of the target, and offsets the telescope so that the target is placed behind the occulting...

16. The Sun: a Pictorial Introduction
... The solar disk in broadband Ca K . This solar image is taken through a 10 wide filter centered on the K line of Calcium ( = 3933 ). ... Because the filter is wide enough to let through some of the continuum on either sides of the Ca K line, features of the solar disk seen in white light remain visible. As a consequence, sunspots can still be seen, but now plages appear much more clearly as bright areas, often surrounding large sunspot groups. ...

18. Measurement of the dark halo shape in polar ring galaxies
... According to the most popular cosmological paradigm, the greater part of the galaxy mass is accumulated in the dark matter halo. ... The polar ring galaxies (PRGs) reveal external rings or disks of gas, dust and stars rotating in a plane roughly perpendicular to the disk of the central galaxy. ... The shape of the dark halo in the model was chosen so as to achieve the best fit to the observed rotation of both galaxies themselves and their polar rings. ... The SPRC-7 galaxy. ...
