I have my doubts on the last one mentioned, a very irregular spectral 
plot with a hint of fluorescence due to OBAs in the paper base, not in 
the coating.

Below I add here more warm Fiber/Baryta qualities without OBAs (with and 
without barite mentioned in the specs) .

Sihl 4848 Masterclass Satin Baryta 290gsm -- 2.4
Bergger PN70 Warm Glossy 300gsm -- 3.9
Both Alpha Cellulose which is rare for warm barite papers, only the 
Innova (IFA19) and the Harman by HM Gloss Art Fibre Warm Tone mentioned 
above are AC.

Cotton based:
Innova IFA45 FibaPrint Warm Cotton Gloss 335 gsm -- 3.0
Canon USA Polished Rag 300gsm -- 2.6
Canson Platine Fibre Rag 310gsm -- 0.4
Hahnem\ufffdhle Photo Rag Pearl 320gsm -- 1.9
Museo Silver Rag 300gsm -- 2.5

There have been more but they are no longer produced.
