=2: YErr is taken from the extra file, according to parameter YErrFile =3: YErr is set to a constant value, according to parameter YErrVal YErrFile Text The name of the extra file, used to generate column YErr (including file path, if the file is not in the same directory, as macro file). Only applies when YErrMethod=2. YErrVal Double Specifies the constant value to be set to column YErr. Only applies when YErrMethod=3. Sets YErr to be 0.01 (constant value) Assumed to be 0.01 Command name: UnloadDataset Description: unloads a dataset. Parameters: Name Type Description What if omitted DatasetNo Integer Dataset number, which corresponds to the slot number in the Dataset Manager. Starts from 1. Assumed to be 1 Command name: CutDataset Description: specifies the cutting range of the dataset, which is considered by the fitting routine. Parameters: Name Type Description What if omitted DatasetNo Integer Dataset number, which corresponds to the slot number in the Dataset Manager. Starts from 1. Assumed to be 1 XMin Double The minimum value of the cutting range Xmin is not changed XMax Double The maximum value of the cutting range Xmax is not changed 4.11.5. Model macro commands Command name: NewModel Description: Creates a new model; moves and resizes the model window. Note: when a new model is created, it is automatically ascribed an identity number, which starts from 1 and increments for every new model. It can be seen in the window title, e.g., model #5 has title “Model5”. This number is used by other commands to identify this model. Guide to RefFIT Page 84
Parameters: Name Type Description What if omitted XPos Integer Horizontal position of the left side (in The default value is screen pixels) assumed YPos Integer Vertical position of the top side (in The default value is screen pixels) assumed Width Integer Window width (in screen pixels) The default value is assumed Height Integer Window height (in screen pixels) The default value is assumed Command name: SaveModel Description: Saves the specified model to a file. Note: This command is equivalent to using the F2 button in the “Model” window (section 4.5). Parameters: Name Type Description What if omitted ModelNo Integer The identity number of the model to be saved Assumed to be 1 File Text The name of the model file (including file path, if the file is not in the same directory, as macro file), i.e. “MODEL1.RFM”, or “C:\MYDATA\MODEL1.RFM”, or “..\MODELS\MODEL2.RFM” No action is taken Command name: LoadModel Description: Loads a model from a file to the specified (already created) model. Note: This command has the same effect as using F3 button in the window ‘Model’ (section 4.5). It does NOT create a new model in RefFIT, so the model with the specified identity number has to be already created with the NewModel command. Parameters: Name Type Description What if omitted ModelNo Integer Model identity number Assumed to be 1 File Text The name of the model file (including file path, if the file is not in the same directory, as macro file), i.e. “MODEL1.RFM”, or “C:\MYDATA\MODEL1.RFM”, or “..\MODELS\MODEL2.RFM” No action is taken Command name: SetModelParam Guide to RefFIT Page 85
