... 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. ...

MAKING THE PROFILES . First of all you are expected to load a FITS file ("FILE"-"LOAD"). ... By pressing the middle button you copy the profile from the first profile window to the second one. ... An example: first integral can correspond to the profile of active region and second integral can correspond to the profile of quiet chromospheric region. ... The second profile (which is subtracted from the first one) you extract after clicking on "SUBTRACT"-"MARK QUIET PROFILE" and marking the region. ...

... Figure 1a illustrates the summary diagram (2 log L, log S ) based on the field intensity contour lines for 7 active regions plotted at 200 G steps in the range of 2200­400 G. One can see that the relationship under discussion is well represented by two straight lines, one corresponding to the log S range from 2 to 7.2 and another, from 7.2 to 9. ... Then, we plotted 2 log L versus log S for all field lines of a given intensity, no matter which sunspot or sunspot group they belonged to. ...
