Detailed Description

Structure to contain information about the structure of the AIPS header file.

Named beginning with a K are offsets with the second character giving the data type:

• I = integer, offset in type AIPSint,
• H = Hollerith (character - not null terminated), offset in type gfloat.
• R = float, offset in type gfloat.
• D = double, offset in type gdouble.
