BULA
→ OPENA value that leaves the two ends of an arc unjoined.
BULAYou give it to thalaArc as the seventh number. The arc is left as a curved line only — its two ends are not joined by anything.
If you fill a BULA arc, the colour still fills between the curve and the straight line that would join its ends — even though that line is not drawn. So BULA is usually used with tlogelaGoTlatsa.
The other two modes are TLHAMALALA and SERIPA.
