Your output agrees with what the ADDE server shows for the bands specified
(but your Area Directory output is not in the same order your
'client.py -- RTGOESR FD 0 0 TRACE=0 BAND=' listings). Here is what
the ADDE server says for all bands for one time:

This listing matches the ADDE server output for the entries that have 0.5, 1
and 2 km resolutions. There do not appear to be any Full Disk GRB images
that have 4 km resolutions.

I disagree. The only thing that I see that doesn't match is the entry
for images that have 4 km resolutions at nadir. 'ncdump's on images
received in the GRB do not show any images that have 4 km resolution at nadir.
'ncdump's of each band you are accessing to get the image size also agree
with the ADDE server listing:
Band 2
netcdf
OR_ABI-L1b-RadF-M3C02_G16_s20180121545417_e20180121556184_c20180121556221 {
dimensions:
y = 21696 ;
x = 21696 ;
Band 5

dimensions:
y = 10848 ;
x = 10848 ;
Band 7

y = 5424 ;
x = 5424 ;
Band 13

OR_ABI-L1b-RadF-M3C13_G16_s20180121600417_e20180121611196_c20180121611254 {
dimensions:
y = 5424 ;
x = 5424 ;
Band 15
netcdf
OR_ABI-L1b-RadF-M3C15_G16_s20180121600417_e20180121611190_c20180121611253 {
dimensions:
y = 5424 ;
x = 5424 ;
Which band(s) are you expecting to have 4 km resolution at nadir? Or is there
something else that I am missing?
Cheers,
Tom
