| deviceAttributeNameX: Name of the attribute which will be fitted by this DataFittingDevice. It may be : a) a fully qualified attribute name . For instance : - D13-1_C07/DT/IMAGEUR.1-ECR/PROFILX b) an alias (if defined in the TANGO Control System): PROFILX |
DEV_STRING | WRITE | Yes |
| deviceAttributeNameY: Name of the attribute which will be fitted by this DataFittingDevice. It may be : a) a fully qualified attribute name . For instance : - D13-1_C07/DT/IMAGEUR.1-ECR/PROFILY b) an alias (if defined in the TANGO Control System): PROFILY |
DEV_STRING | WRITE | Yes |
| deviceAttributeNameSigma: Name of the attribute which will be fitted by this DataFittingDevice. It may be : a) a fully qualified attribute name . For instance : - D13-1_C07/DT/IMAGEUR.1-ECR/PROFILSIGMA b) an alias (if defined in the TANGO Control System): PROFILSIGMA |
DEV_STRING | WRITE | Yes |
| useSigma: This attribute is used to know if error sigma values are provided to the fit. If false, all the values are set to 1. |
DEV_BOOLEAN | WRITE | No |
| nbData |
DEV_LONG | READ | No |
| fittingFunctionType: Type of the function used for fitting (gaussian, lorenzian, sigmoid with or without background) |
DEV_STRING | WRITE | No |
| functionEquation: The equation of the fitting function choosen. |
DEV_STRING | READ | No |
| nbIterationMax: Number of maximum iteration for the fitting algorithm. If the algorithm doesn't go to a final solution after nbIterationMax it is stopped to avoid infinite loop. |
DEV_LONG | WRITE | No |
| epsilon: This value is the stopping value. When the difference between the values of two consecutives steps is under this value, the algorithm stop and succeed. |
DEV_DOUBLE | WRITE | No |
| startingX: Starting value for X to generate the fittedDataX spectrum values. |
DEV_DOUBLE | WRITE | Yes |
| resolutionX: Resolution according the X axis to calculate the values of the dataFittedY spectrum. |
DEV_DOUBLE | WRITE | Yes |
| nbPointsToGenerate: Number of points to generate for the fitted functions. |
DEV_LONG | WRITE | Yes |
| fitMode: 0 : Automatic Mode (data are fitted continuously) 1: Manual Mode . You need to do the StartFit command to launch fit calculations |
DEV_BOOLEAN | WRITE | Yes |
| nbParameters: Number of parameters according the choosen fitting function. |
DEV_LONG | READ | No |
| initialsParametersMode: Set the mode for choosing the initials parameters. FALSE = Manual --> the initials parameters (initialParameterPos, initialParameterWidth, initialParameterHeight, initialParameterBackground) are used to initialize the algorithm. TRUE = Automatic --> initials values are choosen automatically by finding the max value in the Y. This value gives the height. The X value associated to this Y value gives the position. Width is taken at a value of 1.0 and background is given by the first Y value. |
DEV_BOOLEAN | WRITE | No |
| initialPosition: The initial value for the parameter position |
DEV_DOUBLE | READ_WRITE | No |
| initialWidth: The initial value for the parameter width |
DEV_DOUBLE | READ_WRITE | No |
| initialHeight: The initial value for the parameter height |
DEV_DOUBLE | READ_WRITE | No |
| initialBackground: The initial value for the parameter background |
DEV_DOUBLE | READ_WRITE | No |
| position: The value of the position of the curve fitted |
DEV_DOUBLE | READ | No |
| width: The value of the width of the curve fitted |
DEV_DOUBLE | READ | No |
| height: The value of the height of the curve fitted |
DEV_DOUBLE | READ | No |
| background: The value of the background of the curve fitted |
DEV_DOUBLE | READ | No |
| fittedDataSameSizeAsData: This attribute is used to indicate if the FittedData are of the same size as the experimental data. If TRUE the attribute startingX, resolutionX, nbPointToGenerate are not used and the startingX value used is the first X value of the experimental data, the number of points generated is the number of point of experimental data |
DEV_BOOLEAN | WRITE | Yes |
| hwhm: the half width at half medium |
DEV_DOUBLE | READ | No |
| fwhm: the full width at half medium |
DEV_DOUBLE | READ | No |
| nbIterations: Number of iteration for the algorithm to converge |
DEV_LONG | READ | No |
| searchStoppingMethod: This attribute is used to choose the search stopping method used : 1 : the test delta method 2 : the gradient method |
DEV_LONG | WRITE | Yes |
| useScaled: If true, the Jacobian matrix is scaled to avoid conditioning problem (must be always set to TRUE) |
DEV_BOOLEAN | WRITE | Yes |
| xLow: The value of the xlow is equal to the intersection between the background and the tangente to the sigmoid. This attribute is only valid for sigmoid(b) fit. |
DEV_DOUBLE | READ | No |
| xHigh: The value of the xhigh is equal to the intersection between the background+height and the tangente to the sigmoid. This attribute is only valid for sigmoid(b) fit. |
DEV_DOUBLE | READ | No |
| determinationQualityFactor: Percentage of quality fit (represent a percentage of matching between experimental and fitted data) |
DEV_DOUBLE | READ | No |
| fStatisticQualityFactor: Other quality factor higher the value better the fit) |
