image.history - Function

Recover and/or list the history file

Synopsis
history(list, browse)

Arguments

list	in	List history to the logger ?
		Allowed:	T or F
		Default:	F
browse	in	Browse history with table browser?
		Allowed:	T or F
		Default:	T

Returns
Vector of strings, T, or fail

Description

This function allows you to access the history file.

By default, you browse it with the Table browser (browse=T) and the return value is T or a fail.

If browse=F, then if list=F, the history is returned by the function as a vector of strings. If list=T, the history is sent to the logger and the function returns T or a fail.

Currently, AIPS++ does not write new history information (although you can set directly set a new history file with the function sethistory). Only that which has come from FITS file conversions will be stored and listable here.

Example

- im.history();                       # Browse
- h := im.history(list=F, browse=F)   # Recover history in variable h
- im.history(list=T, browse=F)        # List  history to logger
