The least count of a cross staff is typically around 0.5 degrees. This means that it can measure angles with a precision of about half a degree.
The papal staff is called a ferula. It is a staff which is topped by a cross. Bishops carry a staff with a curved top which is called a crozier.
the instruments in navigation are gps's, kamals, sextants, cross staff, back staff, mariners astrolabe, quadrant, and octants :)
It depends on what they're crossed with! My staff is cross Victorian bulldog so she is taller and stockier than other staffs. She also weighs close to 30kg which is double the average staff weight.
To effectively notate music for multiple instruments on a single staff using cross-staves in music notation software, you can assign different instruments to different voices within the same staff. This allows you to show each instrument's part clearly while keeping them all on the same staff.
