# Edit profiles (dialog)

The “Project settings” dialog is used to set up the parameters of the data processing and output. User interface options that do not affect the data processing are places in the separate dialog “Environment options”.

Among many parameters of the aperture photometry procedure a special attention should be payed to the following: Filter width and the Detection threshold. These parameters control mainly the detection of stars on the CCD frames. By decreasing the Filter width value the fainter stars will be found. It is to be pointed out, that too small value may take the artefacts on the background as regular stars. The Detection threshold value sets the distance between the finest stars detected and the background sky noise. The value is entered in multiplies of background standard deviations.

The description of the individual parameters can be found in this chaper.
