Problem

Proposed solution

Implement this in a library format: return mu or D for given muD (we can reuse functions from computing theoretical muD).

[yucongalicechen]

UC1:

1. User has sample composition, energy, and mass density and a target muD in mind, and wants to check the diameter.
2. User provides this information labpdfproc.getmud (lpp.gm)
3. lpp returns the target diameter

UC2: {sjb: I doubt if this one will ever be used, but we could check with Till/Pascal?}

1. User has sample information, energy, target diameter and muD, and wants to know the sample mass density.
2. As UC1.2-3
3. User gets the target sample mass density.

UC3:

1. User specifies sample composition and energy.
2. As 2-3 in UC1.
3. User receives (multiple) recommendations for mu depending on phase

UC4:

1. as UC1 but user supplies packing fraction and no density

@sbillinge could you check if the UCs look good to you? Thanks.
@yucongalicechen I simply edited these. I hope that is ok because it is probably hard to get back the earlier version....
