Custom Image Headers

This window allows the users to add/delete/edit any "custom" keyword for the image FITS headers



The table shows the current custom keywords. Any of those can be changed or deleted, or new ones can be added.
If the user selects a line with the mouse, it will automatically fill the fields on the controls (see below) with that values. This values can be entered manually also.

Below the table there are 3 string fields, and 1 Type control:
KEYWORD: the name of the desired keyword.
Value: the value for the desired keyword. If the type is not specified, it will assume type string
Type:
here the type can be selected:
STR: String
U8: unsigned 8 bits
I8: signed 8 bits
U16: unsigned 16 bits
I16: signed 16 bits
U32: unsigbed 32 bits
I32: signed 32 bits
FLOAT : 32 bits floating point
Comment: comment to appear on the comment area of the keyword header

Then, there are two buttons:
Delete: It will delete the specified KEYWORD. If no keyword with that name is found, it will have no effect
Apply: apply the changes. If the specified keyword does already exists, it will modify it with the new values (specified in the Value and Comment controls). If the specified keyword does not exists, then it will be added.

After the changes are made, those keywords will become "default", in the sense that the system will start with those values everytime afterwards (the changes are actually stored in a header's template file).
