Top] [Prev] [Next] . In order to discover and determine some characteristics of extra-solar earth-like planets, J. R. P. Angel has defined several spacecraft experiments (labelled Oases 1 and 2). We have examined some aspects of these experiments and believe at least one, and possibly two, significant improvements could be made economically. The paper briefly discusses several features of redundant coronagraphs, and indicates one way that they might be incorporated into flight apparatus. ...

... A new IRAF task has been developed that automatically identifies linear (line-like) features in an image or set of images. ... In order to automatically detect linear features, the first step is to select pixels in the image (Fig. 1 , left panel) that fall within a given data value range. ... Another aspect of extended linear features is that the image space pixels that describe them are in some way adjacent to one another and have a minimum and maximum length. ...
