   Bug report of ver3.1 and the B(M1) transition probability

   We have found a bug that may output the wrong B(M1) values by "transit.exe".  The problem may occur under the following conditions:

       1. The version of the KSHELL code: between 20200110 and 20230629, including ver.3.1.

       2. The model space contains an s1/2 orbit.

  Even under these conditions, the code may output the correct value.  It is platform dependent and is caused by the unpredictable behavior of the Fortran "size" function of a non-allocated array.   It affects only the B(M1) transition probabilities.  It does not impact any other values, such as energy, magnetic moment, or one-body transition density.  Ver.1.2g, ver. 2 (published in Comp. Phys. Commun.), and ver.4 are free from this problem.

2020/2/24  ratio_configuration_ptn.py uploaded  ( Thanks to Y. Tsunoda ).  (now included in tar ball)

   It shows the probabilities of the wave function for each orbit occupation.

  Place the script to kshell/bin and run the following command.

    kshell/bin/ratio_configuration.py foo.snt bar.ptn foobar.wav
