Hello there,
I'm a new totally in Idl. So, I need your help
Actually, I've plotted two axis, consisting of x-axis which represents color index ( e.g. r-i) and y-axis which represents magnitude (e.g. r) and inside the plot, there is objects (stars) lie in the models which represents log (g) ( g surface gravity ranging from 7.0 to 9.5) and stars lie between them. Now, I need to estimate logg for each stars and I have written the code. Unfortunately, my code does not work.
This my code,
x=fltarr(r-i) ; x-axis
y=fltarr(r) ; y-axis
xx=findgen(6)/20-0.72 ; logg
n=0
while n lt number_of_wd do begin
j=0
while j lt number_of_stars do begin
linterp,x,y,xx,yy
endif
j=j+1
endwhile
n=n+1
endwhile
print,transpose(yy)
end
I'm waiting your suggestions and your help (Please help me)
thanks
Hana

Look at your definitions of x and y.
FLTARR creates a new array of length its argument that initially contains zeros. I don't think that's what you want -- perhaps you just want:
x = r-i
y = r
