... The exact directions of the offsets are parallel to the rows and columns of the CCD on which the aperture is specified. ... It is often useful to explicitly specify the desired rotation of the WFPC2 field-of-view on the sky. ... Figure 7.8 shows the CCD orientation and aperture locations relative to the U3 axis. ... Obtain the Position Angle (PA) of the source axis on the sky, measured in the standard way, North through East. ... desired source angle in field-of-view measured CW from +U3 axis) . ...

A typical radio dataset might be a 3-dimensional "cube" named AURORA, with axes RA, DEC and FREQ. ... These can be specified by giving the axis name(s) and grids for each subset. For instance, AURORA specifies the whole 3-dimensional ``cube''; AURORA FREQ 3 specifies the subset FREQ=3 (i.e. the RA-DEC plane at FREQ grid 3) of the set AURORA. ... Specifying only the axis name, and no grids, selects all subsets along that axis: AURORA FREQ selects all RA-DEC planes in AURORA. ... axis centre. ...

Region markers can be moved, resized, rotated, zoomed, deleted, and can change geometric type. ... For example, markers placed on astronomical catalog positions should be fixed so that one cannot accidentally move them off the specified position. ... Parameters can be fixed using the fix option of the regions public access point (for fixing classes of markers) or by means of a fix keyword in the definition of an externally loaded marker. ... In the command: echo "regions fix all -position -size" | ...

... The previous example, Chapter 12, "Expanding Colored Squares Example," illustrates how to expand and contract the clipping region of a layer without changing the wrapping width of the layer. This example illustrates how to capture mouse events so that the user can make a layer's wrapping width wider or narrower by dragging the mouse. ... how to capture mouse events for a layer . how to change the wrapping width of a layer by using the load() function . ... Capturing Events for the Layer . ...

Contents] [Previous] [Next] [Alphabetical Tag List] [Index] . This section discusses the tags that let you specify positions for HTML content. LAYER . ILAYER . ... Use the LAYER tag to specify an absolute position for a block of content, and use the ILAYER tag to specify a relative position. ... HEIGHT=" height " . ... OnFocus=" JScode " . ... HEIGHT="height" specifies the height of the layer's clipping region and serves as the reference for setting the relative height of children layers. ...

... This plug-in enables you to add various types of lighting effects to your (RGB) image. ... Directional light . ... Well, you get the idea :) The default settings for this light-type is [-0.5,-0.5,-1.0]. ... Higher values makes your image reflect a lot of light (appear lighter or more intense), while smaller values makes it appear more dull or matte. ... A value of 1.0 makes your image very shiny (bright high-lights) while smaller values makes you image less shiny, making the high-lights dimmer. ...

... Coordinate system . It is necessary to specify the coordinate system for the drilling of plug-plates so that the drilling file (currently named plPlugMap), plate drilling, cartridge, rotator wrap and the rotator itself are compatible. ... The TCC rotator angle (object system) is defined to be 0 degrees for this orientation. ... Thus, the rotator angle gives the conventional astronomical position angle on the sky of the y axis (although Russell won't acknowledge this necessarily). ...
