The red background here is Yohkoh SXT AlMg, and the blue contours are hard X ray images at four diff. Energy channels. , increasing from L to H to the right. The dashed lines here are the solar limb and the active region was in the south-eastern part. With these HXR alone it looks like there is only a small loop, and this is the loop top & foot-points depending on energy. But we still suspect that SXT (on a large FOV)’s extended structure might be representing a large loop.
