For calculating model spectra of early-type helium stars in LTE, we maintain a database of atomic data for, mostly, blue-visual absorption lines of light elements. The data is sorted with one file for each ion. ... III = ++ . ... It will work on both complete linelists (including the atomic data at the start and references at the end) or raw ion files (such as Ni2.d). ... A Fortran utility to convert linelists downloaded from the Vienna Atomic Line Database into the new QUB format. synspec_qub . ...

... Simple use of pointers . ... Allocation of arrays using pointers . ... REAL, TARGET :: B(10,10) REAL, POINTER :: A(:,:) A => B The matrix B has been specified completely, i.e. with the dimensions given explicitly. ... You have to be careful when you use pointers. ... REAL, TARGET :: MATRIX(100,100) REAL, POINTER :: WINDOW(:,:) INTEGER :: N1, N2, M1, M2 WINDOW => MATRIX(N1:M1, N2:M2) If you later wish to change a dimension of the partial matrix WINDOW you only need to make a new pointer association. ...
