Dear All,

two recent bugs found that could lead to a mismatch of how your input is interpreted in flair and in fluka.

1. LOW-MAT
    if you used a LOW-MAT with the default values for a material and the default FLUKA name,
     flair was creating a card like
         LOW-MAT BERYLLIU
    with all other whats empty. However if you modified the LOW-MAT, which is the reason one should add
    a LOW-MAT card, to assign the proper material or a different name
    then the result was ok.

2. DCYTIMES
     if you used multiple DCYTIMES cards and in some of them you didn't had declared all 6 WHAT.
     Fortran is interpreting the empty whats as zero and adds an additional cooling time at the end of
     the irradiation. However flair was ignoring the empty whats and on the next card it would lead to
     a mismatch on the cooling index.
     e.g. if I have two cards
     DCYTIMES 1.0 10.0
     DCYTIMES 200.0 2000.0
     DCYTIMES 30000.0
    fluka will interpret it as
     index 1 = 1.0 s
               2= 10.0 s
               3 = 0.0 s
              4 = 200.0 s
              5 = 2000.0 s
              6 = 30000.0 s
     while flair would have missed the index #3
    However the output summary files from the detectors should indicate the correct cooling time.

Both bugs are corrected in the current version on the web

Vasilis
