CCD temperature (dialog)¶
The “CCD temperature” dialog is used to display a table or a plot of CCD temperature as a function of time. The plot is useful to check the performance of the camera cooling sub-system.
Activating the dialog¶
The dialog can be activated:
from the main menu:
.
The “Plot CCD temperature” dialog appears. Confirm the dialog.
CCD temperature dialog¶

CCD temperature¶
(1) The actual data set is shown here.
(2) You can switch the labels on the X axis between Julian date (JD) or date and time (UTC).
Data sets¶
The following data set is available:
CCDTEMP - Temperature of the CCD chip as reported in the source files; in centigrades
Statistics¶
The Statistics is a tool that computes and shows the minimum, maximum, sample mean and standard deviation.
To activate the tool:
From the local menu, select
. A new panel on the right side of the preview window appears.
If no points are selected, all points in the data set are included in the computation. To restrict the data for the statistics, press and hold the Shift key and draw a rectangle in a graph while you keep the left mouse button pressed down.
Measurement¶
The Measurement tool displays two cursors in the graph. The cursors can be adjusted by dragging them using the left mouse button. The position of each cursor, their distance and statistics for the data between cursors is presented.
To activate the tool:
From the local menu, select
. A new panel on the right side of the preview window appears.Measurement tool
(1) Choose the axis you want to measure.
(2) Positions of the cursor 1 and 2 are displayed here.
(3) Distance between cursor 1 and 2.
(4) When cursors are defined on the independent (X) axis, number of points (frames) between cursor 1 and 2 are displayed and also minimum, maximum, mean value and sample deviation are presented.
