Method
The main menu contains buttons which allow a source region or
background region to be defined and allow the two to be subtracted.
Once a background or source region has been defined, they become
the default; subtractions will use these regions until they are
superceeded. This menu includes the following options:
- OUTPUT
- Allows an output file to be specified - by default all
the results are written to the terminal.
- MULTI
- Once a background region has been defined - subtractions
can be performed on a series of sources by selecting the
MULTI option. This displays a further menu which has the
choices NEWSRC and QUIT. The NEWSRC button must be pressed
before each source is selected.
- SUBTCT
- Subtracts the current background data from the current
source data, normalising for area.
- Bckgnd
- Defines the background region. This displays a further menu
which allows the box shape to be selected.
- Source
- Defines the source region. This displays a further menu
which allows the box shape to be selected.
- SETBAD
- Allows pixels within a polygon to be set bad.
- ICL
- Enables ICL temporarily so that a single command such as:
IZOOM, ISCALE, $DIR etc... can be entered
