(2/29/95, Valdes) + +utilities$t_polyfit.x + Revoved the dependent variable normalization which was not doing anything + to improve the numerical statbility of the routine and which was causing + problems in the computation of the reduced chi-squared and standard + deviation statistics. + (7/11/94 LED) + +utilities$t_polyfit.x +utilities$pfregres.f + Added a trap for rmul values < 0.0 and > 1.0 to the polyfit routine + to avoid floating operand errors caused by trying to take the square + route of a negative number. + (6/20/94 LED) + +utilities$curfit.gx + Removed the graph limit setting so that the graph will be automatically + drawn with the default buffer distance from the end of the data. + Previously the end datapoints would fall right on the axes. + (5/10/94, Valdes) + +utilities$t_surfit.x + +utilities$surfit.par + +utilities$doc/surfit.hlp + +utilities$x_utilities.x +utilities$mkpkg +utilities$utilities.cl +utilities$utilities.men +utilities$utilities.hd + A task for fitting a 2D function or "surface" to an irregularly + sampled set of x, y, and z points has been added. (7/6/93, Valdes) + +utilities$curfit/t_curfit.x,curfit.gx + Curfit was failing if the input file list contained more than one + file or image. The problem was that ic_open was being called + before the file loop but ic_close(rd) was being called after every + fit leaving a null pointer in place for the second file. + (7/30/90 LED) + +utilities$doc/polyfit.hlp + Added the missing "statistical" heading under the weighting section. + (7/23/90 LED) + +utilities$lcase.x + Changed the default output file name extension from ".uc" to ".lc". + (3/7/90 LED) + +utilities$t_curfit.x + For list input only, curfit now sorts the input array before fitting. + Sorted data is required by the rg_ranges procedure (even in the + default case of sample=*) or else data points will be ommitted from + the fit. (24/6/88 ShJ) + +utilities$t_curfit.x,curfit.gx + Davis, December 2, 1987 + 1. Added a new parameter weighting to the curfit task. The four weighting + options are uniform, user, statistical and instrumental. The weights in + the four cases are 1.0, user input, 1/y and 1/sigmay ** 2. In the latter + case the weight that the user supplies is interpreted as sigmay. All + four options are available if input is from a list or STDIN. If input + is from an image section only the uniform and statistical options are + available. + +utilities$t_polyfit.x + Davis, November 23, 1987. + 1. Added a new parameter weighting to the polyfit task. The three + weighting options are instrumental, uniform and statistical. The + weights in the three cases are 1./sigy ** 2, 1.0 and 1/y consistent + with the Bevington definitions. If the weighting is instrumental + the user must supply the error in y as well as x and y. + +utilities$*x + Valdes, February 17, 1987 + 1. Required GIO changes. + +utilities$t_curfit.x, curfit.gx: Valdes, July 3, 1986 + 1. Modified CURFIT to use new ICFIT package. + +________________________________________ + +From: Valdes Mar 14, 1986 +Task: Curfit + +1. The CURFIT task has been modified to allow switching between single +and double precision calculations. Generally double precision is used +but this task provides a convenient test facility for testing changes +in the mathematical routines or which precision is appropriate for a +new task being developed. + +2. The help page was updated. + +________________________________________ + +From: Hammond Jan 6, 1986 +Task: Curfit + +1. A new task, Curfit, has been installed. It is the cl interface to + the curfit package and allows for interactive fitting of functions + to list or image data. The function types supported are Legendre + or Chebyshev polynomials and linear or cubic splines. + +__________________________________________ + +From: Hammond Dec 19, 1985 +Task: Polyfit + +1. Polyfit no longer gets a floating divide by zero when a linear fit + has a correlation = 1. The problem was in the error calculation (ftest) + portion of the Bevington routine regres. This problem was reported + by ST. +.endhelp |
