A portion of the images from Figure 1 showing a bundle of loops in an ephemeral active region. To guide the reader, two footpoints of the bundle, A and B, are marked on the solar surface (they were selected in the STEREO A image and remapped to the STEREO B coordinates). The bundle appears to have a very different shape in these two images, as outlined by the white dotted lines. If the bundle was circular in cross section, it would have the same width and the same line-of-sight depth when viewed from the side ( STEREO A) and from the top ( STEREO B). It is possible that the background obscures the true shape of the bundle. It is, however, just as possible that the bundle is simply non-circular in cross section. For example, such a difference in widths for different viewing angles is expected for a squished cylinder, whose cross section is elongated along one line of sight and across the other one. This option is favorably supported by the fact that on STEREO A (left image) the bundle is narrower and brighter, while on STEREO B (right image) the bundle is wider and dimmer, even though the images are corrected for exposure and plotted on the same color scale.
