Atomic data from the Iron Project LIII. Relativistic allowed and forbidden transition probabilities for Fe XVII
TL;DR: In this paper, an extensive set of fine structure levels and corresponding transition probabilities for allowed and forbidden transitions in Fe xvii were presented, which translate to over $2.6 × 10^4$ allowed (E1) transitions that are of dipole and intercombination type, and over $2312 forbidden transitions that include electric quadrupole(E2), magnetic dipole (M1), electric octopole (E3), and magnetic quadrupoles (M2) type.

Numerical ‘health check’ for scientific codes: the CADNA approach
TL;DR: There is a need to perform regular numerical 'health checks' on scientific codes in order to detect the cancerous effect of round-off error propagation and the use of the CADNA library is advocated as a suitable numerical screening tool.

GRASP: A general-purpose relativistic atomic structure program
TL;DR: The Oxford MCP/MCDF and MCBP/BENA packages have been rewritten in FORTRAN 77 and combined in the new code, GRASP, which is more versatile than its predecessors, contains more stable and accurate numerical procedures and a simplified but more flexible interface.
