Hi Virginia,
See

isce2/components/isceobj/StripmapProc/runDenseOffsets.py

Line 37 in edea69d

objOffset = DenseAmpcor(name='dense')

This essentially lets you control the properties of the DenseAmpcor object that is created using another xml file named "dense.xml" without having to change the python code. Ampcor does some intial checks on the quality of the coarse match with these thresholds before proceeding to invest time on an oversampled search.

You should be able to set up dense.xml like this

<stripmapAppDenseAmpcor>
<component name="dense">
<property name="SNR_THRESHOLD">0.</property>
<property name="COV_THRESHOLD">100000</property>
</component>
</stripmapAppDenseAmpcor>

You have to use the public names defined here:

isce2/components/mroipac/ampcor/DenseAmpcor.py

Line 214 in edea69d

SNR_THRESHOLD = Component.Parameter('thresholdSNR',

isce2/components/mroipac/ampcor/DenseAmpcor.py

Line 221 in edea69d

COV_THRESHOLD = Component.Parameter('thresholdCov',

If there are no hardcoded overrides for these values in the workflow, this additional xml should allow you to control parameters.
