Multi extension FITS file 1492 2
Started by Deleted User
Hello all,
I have a multi extension fits file that contains reduced astronomical data.
I'm using an already built program to analyze the data but the important data (along with the necessary header) is stored in extension=1 while the program is by default looking in extension=0.
Beside from changing to program code (which I can't do) is there a way to make it read the right extension
Thanks in advance,
Amir

Hi,
I was wondering if you had an example of generating a data cube and if there was a simple way to convert a data cube in Matlab to IDL.

IDL plot function - upper limit symbol 2058 4
Started by Deleted User
I really like the format of the IDL plot function compared to the procedure version, however I'm having a difficult time figuring out how to plot a downward arrow indicating an upper limit to a value. With the plot procedure, I could use PSYM=8 after defining the symbol using PLOTSYM, 1 which gave me a downward arrow. The symbols for the plot function do not have a downward arrow available. Is there a way to do this or do I need to go back to using the procedure instead

IDL 8.2 on Mac Yosemite 1692 3
Started by Deleted User
My mac OS is Yosemite 10.10.3 and the IDL version is 8.2.0.
When installing the IDL on Yosemite, the first two steps for installation of IDL to Yosemite looks fine, i.e., the introduction, the license agreement. When choosing the installation for users, the "continue" botton becomes grew and the next step of the installation can not be done.
How can I fix the problem
Thanks!

two bugs in WIDGET_WINDOW 1528 3
Started by Deleted User
I've encountered two problems with WIDGET_WINDOW that I've been unable to find a solution for, and they seem to be the result of a bug. One is that when using the SYMBOL function, the graphics do not appear until after there is a mouse click within the window; all other graphic functions that I've tried so far appear right away.
The other problem is that when using the SAVE method with the window to write a PDF file, the output is blank , but appears normal if this is done within a widget_event ...

OVERPLOT with MIN_VALUE resetting the Y range of the PLOT 1486 2
Started by Deleted User
If I do following in IDL:
a = findgen(10)*0.010.3
b = findgen(10)*0.010.2
plot(a)
plot(b, /overplot)
The output is nicely displayed, however, if I do
plot(b, min_value=0.3, /overplot)
Then the Y range will be reset to default which is &910,1&93, then the curve become flattened and the plot full of space, looks ugly.
Is there anything I can do to resolve this I mean preserve the plot ratio and size even the overplot data is given below the min_value.
Thanks for any help and hint.
Regards...

FILE_COPY interrupting 1440 1
Started by Deleted User
Hi,
Does anyone know if there is a way to interrupt a large FILE_COPY (or FILE_MOVE) I have a situation where there could be a large number of files being copied, but I need to allow an operator to interrupt it. The only solution I can think of is spawning the process out to an OS copy command, allowing me to display a 'cancel' dialog to the operator'.
Thanks

IDL 8.4 : SERIOUS problems with save files 1512 3
Started by Deleted User
Good morning,
I am running IDL 8.4 on a windows 2008 server machine. I have two problems with the save files I am creating:
1. Even though I am including the exit, /no_confirm, command before the end command at the end of the program, IDL does not exit. I.e. the save file starts, runs, executes and then just sits there. If I simply run the same code properly, i.e. open, compile, run, then it executes and at the end, exists IDL. From the save file, it does not. Any ideas
2. Why do the save file ...
