... Simulations were also carried out to quantify the range in parameter space which could be filled by stars varying in accordance with the spot hypothesis. ... First, an unspotted star was produced. To do this, colors of a given spectral type (taken from Bessell and Brett 1992) were converted to fluxes for a normalized distance. ... To simulate spots, between five and 40 of the grid locations were refilled with values corresponding to temperatures between 100K and 1000K cooler than the photosphere. ...

... 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. ...
