2-dimentional fit to gridded data 1771 2
Started by Deleted User
I am looking for an IDL function which enables a 2-dimensional fit to gridded data, i.e. similar to the GAUSS2DFIT or the SFIT function. In the particular case the data is a grid array, let's say a=dblarr(x,y), where x, y and z=a(x,y) are the coordinates in the 3d space. The function I want to fit to my grid array could be a hemisphere, cone, or even any other mathematical area function, which can be described as z=f(x,y). CURVEFIT is something which is very to close to that what I need,...

starting with IDL 8.6.1 when calling rdpix from the command line I get this (on all OS): 'Windows': cr = string('15b)string('12b) ; carriage and new line ^ Syntax error. At: C:\Program Files\Harris\ENVI54\IDL86\lib\rdpix.pro, Line 73 Attempt to call undefined procedure: 'RDPIX'. Since the source code of rdpix has not changed this error must be caused by some different compilation setting in 8.6.1.

Issues with the MEAN function 2240 1
Started by Deleted User
I am stymied by something that IDL is doing in my code, and I cannot explain it. I am calculating the mean (average) of a defined subset of an array (using an index defined by the where function), and I am printing out the mean as well as the number of elements in the subset for which a certain condition is met. If no element meets the condition (index = -1) , I would expect the mean to come out as NaN. However, IDL always returns a number. I thought something was wrong in my elaborate code, but...

Changing Font Size and Type in Axis Titles 6529 1
Started by Deleted User
p.title.font_size=value works fine to change the main title font size, but I don't see a way to change the size of the x axis and y axis titles. Also, what font was used prior to 8.6 I think the new one looks terrible, and it seems to be drawn differently: it's blurry and not as crisp and clear as in previous versions.

These vectors are plotted on top of a contour map of the astronomical...
