... We also take care to characterise the flat fields, especially their colour dependence, to very high precision which enables high precision photometry even without autoguiding. ... The Blue Diamond Effect The blue diamond effect is caused by surface imperfections on the silicon chip introduced during manufacture, resulting in a repeated large scale pattern in the flat field at blue wavelengths. ... We can remove the blue diamond by using a colour appropriate flat field produced in the lab. ...
