Calibration

Calibration may be applied on the fly before plotting. This is controlled by the following commands (see respective help for more information):

• SET PHASE RELATIVE$\vert$ABSOLUTE
• SET AMPLITUDE RELATIVE$\vert$ABSOLUTE: see also Table
• SET RF ON$\vert$OFF

The control parameters for calibration are displayed in the left header of the plot (red rectangle number 4 in Fig. ). Each calibration solution can be antenna or baseline based (provided a solution was computed and stored beforehand, see section and ).

Table: Scaling of amplitude depending on unit/mode. $J_i$ is the antenna efficiency in (Jy/K), $A_{ij}$ is the amplitude calibration factor (in K/Jy) and $S$ the source flux (in Jy)

Unit $\backslash$ Mode	ABSOLUTE	RELATIVE	SCALED
KELVIN	1	$A_{ij}(t)$	$1/S$
JANSKY	$\sqrt{J_i*J_j}$	$A_{ij}(t)/ \sqrt{J_i*J_j}$	$1/S$
