      Eliminate code duplication in 'save fine cont' · 89b5afdf
      Chatzikos, Marios authored
      The previous implementation of 'save fine continuum' accumulated the
      first bin separately from any requested others (9 more, by default).
      That forced code duplication relating to identifying the most opaque
      line in the bin.
      
      Restructure the code to treat all bins at once; eliminate duplication.

      Identify most opaque line in 'save fine continuum' · d1073383
      Chatzikos, Marios authored
      Anna Ogorzalek posted a query on the Cloudy group about identifying
      absorption features in the output of the 'save xspec mtable' command.
      
      A partial answer would be to identify features due to the lines alone.
      
      The present adds two columns to the output of 'save fine continuum'.
      The first identifies the species whose line is centered at that bin,
      and the second reports the optical depth due that line alone (i.e., not
      the total including any neighboring lines).

      demote cautions of parts of SED being zero to notes · ce780fa2
      Ferland, Gary authored
      The demotes cautions that parts of the SED are zero to notes.
      The following wc on auto shows that we have a large number of
      these.  They are benign - they occur if we use a blackbody
      that does go to zero far out in the Wien tail.  They are a
      minor note about the SED rather than something deserving of
      raising a caution.
      
      the number of cautions in tsuite/auto went from

      Protection against division by zero cooling. · 7a61cef8
      Ferland, Gary authored
      These protect against division by zero.  Problems were exposed
      by the lab sim posted in gtests / bugs / Mancini.  The
      sim does get now much farther along but aborts when the line
      stack becomes misaligned.
      
      The sim is a lab plasma, so it is far from our home base, but we
      should be able to compute it.  It is non-equilibrium.  It is
      unclear why the cooling is zero - perhaps the total is net heating.
      
      The changes seem safe since they are have never been needed and
      will have no effect in most cases.

      add three AGN SEDs · 8ec44715
      Ferland, Gary authored
      Maryam Dehghanian added these three AGN SEDs that are being
      actively used by the community in AGN research.  The updated
      ReadMe.txt gives more information.

      update OI CS per Antonio Garcia report · a3827c18
      Ferland, Gary authored
      email of 2021 May 5
      In the last few days, I've been collecting rates for
      O i +e inelastic collisions. I started with Barklem,
      A&A 462, 781-788 (2007) and tried to cast the rates into
      Omega_ij strengths. After accounting for the partitioning
      into the 3 fine-structure levels (lumped together by
      Barklem), I was in a position to compare my Omega_ij with
      those reported in the stout datafile. I was able to match
      the Omega_ij for all transitions from the 1,2,3 levels
      into the 4,5,6 levels, and also the 4-->5 transition.
      
      I'm not able, however, to reproduce the Omega_ij values reported
      in stout for the 1,2,3-->7 transition (from O(3P_J=2,1,0)
      into the level at 9.52 eV). I didn't check the transitions
      into more energetic states. The comments at the bottom of the
      stout o_1.coll file (attached here for your reference) note
      that there may be some inconsistencies. I'm also attaching the
      values that I estimated myself for transitions within levels up
      to 10 eV. I would appreciate y...

      GS correct errors recently introduced reactions · 9a72cd25
      Ferland, Gary authored
      The form of th85rate has a different formula than hmrate. For photoreactions one should use th85rate, not the hmrate. Since, both the th85rate and hmrate  take coefficient values in a similar syntax style (for alpha, beta and gamma), an unintentional mistake happened by me for those reactions.

      Fix bug in statistical weight of singlet ground · 9cd3a14a
      Marios Chatzikos authored
      The function that computes the statistical weight for levels in He-like
      species reports 4n^2 for all levels.  The 4 sums over both singlets and
      triplets.  However, the ground has only a singlet state, no triplet.
      
      This is the corollary of an earlier bug, which made the same mistake in
      how the n-n' CS is broken up among the fine structure levels of a He-like
      ground state.
