2021-05-17Resolve FIXMEs and TODOsThomas White
Prompted by the article linked below, for each FIXME/TODO I've either referenced an issue in the tracker, or removed it if it's not worth fixing. https://schleiss.io/plotting-source-code-todos-for-open-source-projects
2021-05-07Add has_unique_axis()Thomas White
2021-04-27Rename libcrystfel's config.h to libcrystfel-config.hThomas White
This removes the big potential for confusion, which has happened several times (see e.g. 095cbebaf6). It also fixes in-tree builds with CMake (but seriously, always use out-of-tree builds). Fixes #2.

2021-01-11resolution(): Use reciprocal representation instead of crystallographicThomas White
This avoids a load of trigonometric functions. In combination with the new UnitCell representation caching, this gives a significant speedup for cases where resolution() is called in a loop.
2021-01-11UnitCell: Store all representations once they're calculatedThomas White
Previously, the "getter" functions would re-calculate the requested representation every time they were called. This could mean doing a matrix inversion in the middle of a tight loop, wasting loads of time. Now, it stores the calculated values and returns them directly next time. Setting the parameters invalidates the values for all representations other than the one given. The cost of doing this is that the cell can no longer be "const" in the getter functions. This tracked through some other code, but nothing too severe.
2021-01-06partialator: Reject crystals with obviously too large profile radiiThomas White
The criterion for "too large" is 20% of the 1/d value for the lowest reflection which is not systematically absent according to the centering. A profile radius larger than the 1/d value for a reflection will crash the xsphere partiality model, and some visualisation shows that this is a clearly non-physical situation. The profile radius shouldn't be anywhere near the inter-Bragg spacing for reasonable data. However, feedback shows that this is happening quite often in real data, probably due to bad indexing.
2020-10-26Label all uses of cell tolerancesThomas White
I'm sick of fixing this same issue over and over again. New rule: any code handling unit cell tolerances MUST be labelled with details of units.

2020-03-13uncenter_cell(): Convert R to PThomas White
Otherwise, the cell comparison doesn't recognise the cells as the same, breaking indexing with an R reference cell. Unfortunately, the resulting cell after comparison by compare_r_c_p still comes out as P, but that doesn't seem like a big loss. To get it strictly correct, we'd need some way of tracking through the information that the cell got "uncentered" from R to P, even though the matrix is an identity.
