| X: Beam position in X |
DEV_DOUBLE | READ | No |
| Y: Beam position in Y |
DEV_DOUBLE | READ | No |
| XFwhm: Beam size, full width half maximum in X |
DEV_DOUBLE | READ | No |
| YFwhm: Beam size, full width half maximum in Y |
DEV_DOUBLE | READ | No |
| Intensity: Integrated beam intensity over the image |
DEV_DOUBLE | READ | No |
| MaxPixelValue: The value of the brightest pixel in the image |
DEV_LONG | READ | No |
| Roi_automatic |
DEV_BOOLEAN | READ_WRITE | No |
| ImageCounter: Corresponds to the image counter of the ccd device of the last calculated image. Can be used to correlate the calculated beam parameters with a taken image. |
DEV_LONG | READ | No |
| Average: The coefficient used for the linear averaging of the images. 1 = no averaging, 100 = averaging with a coefficient of 0.01. |
DEV_LONG | READ_WRITE | No |
| Threshold: Threshold on image. If a pixel value is < threshold the pixel value is set to 0. |
DEV_LONG | READ_WRITE | No |
| RoiExtension: Extends the automatic AOI to x times the calculated FWHM around the found maximum |
DEV_DOUBLE | READ_WRITE | No |
| BorderExclusion: Excludes x rows and columns at the image border from the calculations |
DEV_LONG | READ_WRITE | No |
| Enable_X: Calculates beam position and size in X when true |
DEV_BOOLEAN | READ_WRITE | No |
| Enable_Y: Claculates beam position and size in Y when true |
DEV_BOOLEAN | READ_WRITE | No |
| GaussFittMax: Fitt a gausian to the peak points of the profiles to find the real maximum value. Increases the precission of the full width half max. beam size calaculation |
DEV_BOOLEAN | READ_WRITE | No |
| BackgroundSubstraction: Substracts the background level found at the AOI borders from the image |
DEV_BOOLEAN | READ_WRITE | No |
| CcdDeviceName |
DEV_STRING | READ | No |
| Enable_FwhmTuning: When set to true the FWHM is recalculted with a profile of only a part of the image around the beam center. The extension of this area is defined by FwhmTuningExtension attribute. |
DEV_BOOLEAN | READ_WRITE | No |
| FwhmTuningExtension: Extends the profiling area for the FWHM recalculation to x times the calculated FWHM on the full image around the found maximum. |
DEV_DOUBLE | READ_WRITE | No |
