The tables below show the resolution achievable by collecting data to the 2 theta settings indicated at various wavelengths (edges). Also included is the minimum wavelength required to reach 0.84 A resolution for that run list.
There are other options available to import which give greater redundnancy.
Please ask if you have any specific data collection requests.
This can also be imported using the Load Default Run List button just above the right-hand corner of the data collection table.

Note: If data is being collected at 2θ=40°, then the 2θ=20° scans are also required to make sure the inner sphere is adequately covered, the phi scan at 2θ=0° is not necessarily enough to ensure there is good scaling.

This is the same as 160mm 0-105deg 5 steps but with the 2 theta steps in reverse so the high angle data is collected first. This could be useful if radiation damage affecting the high angle data is likely to be an issue.

The overlap between the 2θ=20° and 2θ=45° is a bit small, but this could be worth a try if radiation damage is likely to cause more issues than scaling.
For wavelengths between 0.75 Å and 0.87 Å, changing the 2θ=45°set of scans to 2θ=40° should work better as this will still give a resolution of 0.84 Å, but with better detector overlap
– Remember to update the start axis to omega = -135°!
(Or use the start of the 300mm 0-105deg 7 steps option)

This option gives better overlap between scans up to 2θ=45° than 300mm 0-45deg 3 steps.
