8 years ago Hello,
Some of the spectral subclasses listed as missing (B7, and A4,5,8 for some metallicities) were just difficult to find for the full parameter space, and if you know any collaborators that would have those templates I would be happy to add them!
We did not spectrally classify any stars as O1-4 and K6 since there is debate as to whether these spectral classes exist.
As for the K5 and K7s, there are templates for both of these spectral subclasses, just not the full metallicity extent available with the early K stars. This is because the the method used for determining the metallicities of the late K and early M stars is only accurate between metallicities from -1.0 through +0.5.
The templates I created only went down to the very beginning of L and I have been thinking of adding in Sarah Schmidt's SDSS L dwarf templates for the rest of the L spectral class. I will send her an email asking about adding those, since it would make the code more useful for brown dwarf people.
Let me know if you have other comments about the missing templates.

Hello All,
I've noticed that some of the template subclasses are missing, namely O: 1-4 ; B:7 ; A: 4,5,8 ; K: 6,7,5 ; L: 4,5,7,8,9. I did some investigation and noticed that templates only exist for certain subclasses and metallicities. Can something be worked out to have a complete sequence of spectral types and subclasses? Perhaps some collaborators have templates to offer? Thanks again for the time and attention
