cgcurs + fixed window

Post by Benchoc »

Hi
Here is my problem:
I use a first time cgcurs with region =image(1) and options=mark ,region
so that I get an cgcurs.region file containing the coordinates of the box I define by clicking around my region of interest in the firt image of my cube.
Then I want to use cgcus on each image of my cube and make statistics in the box previouly define BUT without having to click again in each sub images
What I do is so a second call to cgcurs with
unset region unset options
cggurs options=stat,region=@cgcurs.region
but at this stage I have to re-clik on each subimage of my cube ..
is there any tip to avoid this second clicking stage and make stat on the whole box defined by cgcurs.region
I want to use cgcurs in order to get the flux density and imstat doesnt give me this information
many thanks for your help

Hi Benchoc,

You might try another method here.

After defining the region with cgcurs, try making a new image that consists only of this region using imsub:

imsub in=image.in out=image.out region=@cgcurs.region

Then you can get the image statistics with the imhist task:

imhist in=image.out device=/xs

Try this and see if it works for you. I don't think there is any way to use cgcurs the way you wanted to do without doing the second round of clicks.

Many thanks Jamie for your fast answer
unfortunately imhist does not give the flux density as output (the same for imstat)
I ve only found cgcurs giving this output which I need for computing flux ...
so I think I am forced to click a re-click and click again...
cheers
