Hello,

your TIF files contain some information in tag 270 (see below).

(To read the tags you can use the ImageJ plugin here:

http://rsbweb.nih.gov/ij/plugins/tiff-tags.html)

It seems the calibration data are identical for both images:

XpixCal=233.059 YpixCal=233.059 Unit=A (The unit should read 1/A).

Using this information you can try to figure out the calibration in both images and see if the results for Al fit the published patterns for Al.
