23) Double left-click on the E8 "adjust" thumbnail and move the points E8.bp1 and E8.bp2 to
the same locations as for the VIS image. Test the accuracy of the alignment by double
left-clicking on the E8 “test_alignment” thumbnail.
24) To align the VIS and UVR images (whether these are the same images as those in E8,
or different images, as in Figure 3-51), scroll down and follow the same procedure as
detailed in points 17) to 20) above for the images in E9. Note that the points E9.ap1 and
E9.ap2 on the E9 “reference” VIS image are automatically placed in the same locations
as for the D1 “reference” VIS image.

Matching the brightness (luminance) of the IRR and/or UVR image to the calibrated VIS
image.
25) Click on the “specden” tab (Figure 3-52). The spectral density correction of the IRR and
UVR images is carried out by matching the luminance of these images to that of the
calibrated VIS image.
26) The matrix of average X, Y and Z values for each of the standards created for the VIS
image in the “markup” tab and calibrated in the “viscalib” tab (from previous workflow for
the correction of VIS images) is automatically carried over to columns O and A (at 017
and A7, respectively) for comparison with the matrices generated as described below for
the IRR and UVR images.
27) The positions of the Spectralon diffuse reflectance standards in the IRR or UVR image
are extracted from the alignments carried out in the “align” tab, as described above (see
B9, Figure 3-52 and E2, Figure 3-53).
