At least two of the example scripts in meas_astrom suffer from severe bit-rot. Specifically,
meas_astrom/examples/rerun-wcs.py and meas_astrom/examples/rerun_wcs.py do not run at all (from the get-go they try to import obsolete packages, e.g. from astrometry.util.pyfits_utils import * and import lsst.meas.astrom.net as astromNet). Please either update the examples or delete them.
