What to do after a good quality observation

Flux curve plots

Click on the source name to see the flux curve plot. The data points are collected from koosteet and the GIX project database. The default frequency is 37 GHz. The date of the first and the latest observation (in decimal years) and also the minimum and the maximum flux at the selected frequency can be seen below the text "GIXplot: source @ frequency".

A different frequency can be selected. A new y-axis max. value will adjust the maximum flux density value shown on the y-axis correspondingly. Data points in the desired interval can be inspected by altering the start and the end epoch value. Changes are applied when plot button is pressed. The default values are restored by pressing the defaults button.

Possible problems

An error situation may occur when several people are updating the list at the same time. The most probable outcome is that an error message is displayed and the changes of only one person are saved. The others have to do the editing again.
