Deramp with or without multillooking

[buend...@hotmail.com]

Dear Batu,
Normally I performed the deramp setting the multilloking 1:1 without problems, but when I tried the oversample step or a srp_multillook=" 5 1" I got some error like:

ADORE: deramp unwrap
Reading unwrap information from: ./20040820_20050805.res

    raise TypeError('Improper input: N=%s must not exceed M=%s' % (n, m))
TypeError: Improper input: N=3 must not exceed M=2

Any idea on how to make an uwrapped multilooked interferogram and then perform correctly the deramp step?
Another question is related to the same technical aspect:is it possible to make a multiple pairs script with multilooked interferogram in order to avoid problem on the deramping step provided by GIANT?

Hi Flippo, 

I am not sure what is going on, but it should work. I am surprised you are having trouble... 

Just make sure you have the latest adore before we go in any further (ADORE: check updates).

Instead of the multiple pairs script, I recommend you use the crops, superMasterResample, and i12s. You can also generate multilooked interferograms using:

- superMasterResample 

- s_crop2resample

commands. 

If you want to use the multiple pairs script, you should be able to do so by setting the srp_multilook to "5 1" and saving settings before you run the multiplePairs.drs. Does it not work?

best, 

batu
