notice, range [,subgroup][,group]

range - Defines range of data points to notice. This can be either: - Data point range, denoted by the data point number: <n1>[-], while , are positive numbers. Data point numbers start from zero. Open intervals can be represented with a "*" instead of the number. If only one number is given, a single data point will be referenced. If <val2> is less than all but the interval <val2>.. are referenced. - X value range, denoted by float point numbers: <val1>- , while , represents X values defining the interval to reference. Open intervals can be represented with a * instead of the value. If <val2> is less than <val1> all but the interval <val2>.. is referenced. - Vector of data point indices. The vector is denoted with [val,val,...,val] (indgen may be used also). - Boolean expressions with X/Y values. All values for which this expression is true are referenced. The expression may contain algebraic formulas combined with comparison operators "lt", "le", "eq", "gt", "ge" as used in IDL comparisons. For each data point a keyword is defined which has meaning and can be used for the boolean expression: x - The x-column value. y - The y-column value. error - The error column value. selected - True when the data point is selected. def - True when the data point is defined. x1 - Multi column first column value. x2 - Multi column second column value. x3 - Multi column third column value. To avoid interference with functions which also can be used a lower/upper case distinction is made. IDL funktions should be upper case. Default are all data points.

> notice, 2 -> notice data point 2 (the 3-rd) > notice, 5-22 -> notice data points 5..22 (starting from 0) > notice 46-* -> notice all data points upwards from point 47. > notice, 2.2-5.7 -> notice all data points from x=2.2 to 5.7 > notice, *-0.2 -> notice all data points up to x=0.2 > notice, 0.5-0.2 -> notice all data points except those in 0.2..0.5. > notice, Y LT 0.5 -> notice all data points with Y-values less than 0.5. subgroup - (optional) The data set (subgroup) for which the model should be applied. This can be either the subgroup number or the file name representing the data set. It is possible to set more than one subgroup, either with numbers in brackets ([]) or denoting filenames with wildcards ("*"). Default are all subgroups in current used group. group - (optional) The data group for which the model should be applied. Default is the primary group 0. Must be in range [0..29].

Changes information about data points used for fitting. Data points are not excluded.

> notice, 0.2-7.5, 3, "test.dat" -> notice all x values between 0.2 and 7.5 from group 3, subgroup represented by file "test.dat"
