Figure 2 : GPS network connecting I.G.S./A.S.I. 
permanent stations with "farogoro" local 
point. 
In Appendix A we report the files : "elenfis.dat", 
"misgoro.dat", "misngoro.dat", "xinigoro.dat", "nppi- 
goro.dat", "emisgoro.dat", "parellis.dat". 
After, we have inserted one blunder of 1 meter in 
the AY component of the GPS baseline vector bet 
ween MATERA and farogoro; hence we have ve 
rified the presence, the localisation and the magni 
tude of the blunder with Global Test and the 
BAARDA TESTS which are reported in Appendix B. 
In Appendix C we report the adjusted coordinates 
with the e.q.m. 
Finally we report in Appendix D the file "pesigo- 
ro.dat" and the BIQUE scale factors for the GPS 
vectors cofactor matrices. These last two lists deal 
with a case of a larger number of I.G.S./A.S.I. sta 
tions as reported in the last part of this appendix.
