Default spectral type (A1V from Houk+1999) appears to be erroneous.
A1V may have been a typo for K1V?
Star has been classified as late G or early K dwarf by 4 others:
K1V
1935ApJ....81..187A
K2V
1972AJ.....77..486U
K0
1985ApJS...59..197B
G9V
2003AJ....126.2048G
This is also in agreement with published Teff estimates:
5215+-34 K 2006A&A...450..735M
5306+-80 K 2011A&A...530A.138C
and consistent with colors (B-V = 0.812, Bp-Rp=1.0085, Bp-G=0.4464, G-Rp=0.5621)
Recommend adopting Gray's recent spectral type:
G9V
2003AJ....126.2048G
