... This task takes an OM OSW source list, with source positions in pixels, and converts to sky coordinates. These sky coordinates are then used to produce a sky coordinate image. The task requires the user to enter the name of an OSW source list and its corresponding OSW image. ... The tangent plane coordinates are then converted to sky coordinates. ... The algorithm sets up a grid of offsets in the x and y directions to be used to match up stars in the source list to those in the catalogue. ...

This diagram illustrates two block boxes, one above the other, with rectangular clipping regions of different dimensions. ... Both axes depict increments of 5px. The clipping region of the first P box lies entirely within it, offset 5px from the top and left edges of the P box, and 10px from the right and bottom edges. ... The clipping region of the second P box resembles that of the first in style and position, except that the right edge is 5px to the right of the P box's right edge. ...

The VLTI Calibrator Selector Tool is a tool intended to assist in the selection of suitable interferometric calibrators for VLTI observations with MIDI and AMBER. It uses a model of the VLTI and its instruments to assess the fringe visibility, given the observed bandpass, the geometry, spectrum, and coordinates of the target and the time at which the observations are to be made. ... The tool offers an HTML/Java based interface and consists of two pages. ... The quality flag depends on LDD_chi2. ...
