AST_TUNEC

Set or get a character-valued AST global tuning parameter

Description:

This function returns the current value of a character-valued AST global tuning parameter, optionally storing a new value for the parameter. For integer-valued tuning parameters, see AST_TUNE.

Invocation

CALL AST_TUNEC( NAME, VALUE, BUFF, STATUS )

Arguments

NAME = CHARACTER ∗ ( ∗ ) (Given)
The name of the tuning parameter (case-insensitive).
VALUE = CHARACTER ∗ ( ) (Given)
The new value for the tuning parameter. If this is AST__TUNULLC, the existing current value will be retained.
BUFF = CHARACTER ∗ ( ) (Given)
A character string in which to return the original value of the tuning parameter. An error will be reported if the buffer is too small to hold the value.
STATUS = INTEGER (Given and Returned)
The global status.

Notes:

Tuning Parameters :

HRDel
A string to be drawn following the hours field in a formatted sky axis value when " g" format is in use (see the Format attribute). This string may include escape sequences to produce super-scripts, etc. (see the Escapes attribute for details of the escape sequences allowed). The default value is " %-%^50+%s70+h%+" which produces a super-script " h" .
MNDel
A string to be drawn following the minutes field in a formatted sky axis value when " g" format is in use. The default value is " %-%^50+%s70+m%+" which produces a super-script " m" .
SCDel
A string to be drawn following the seconds field in a formatted sky axis value when " g" format is in use. The default value is " %-%^50+%s70+s%+" which produces a super-script " s" .
DGDel
A string to be drawn following the degrees field in a formatted sky axis value when " g" format is in use. The default value is " %-%^53+%s60+o%+" which produces a super-script " o" .
AMDel
A string to be drawn following the arc-minutes field in a formatted sky axis value when " g" format is in use. The default value is " %-%^20+%s85+’ %+" which produces a super-script "’" (single quote).
ASDel
A string to be drawn following the arc-seconds field in a formatted sky axis value when " g" format is in use. The default value is " %-%^20+%s85+∖" %+" which produces a super-script " " " (double quote).
EXDel
A string to be drawn to introduce the exponent in a value when " g" format is in use. The default value is " 10%-%^50+%s70+" which produces " 10" followed by the exponent as a super-script.
