I am trying to search the herschel archive for multiple sources (I'll wait to hit it with 1000's, but am testing now with 10). I am seeing a strange "LoginError: Data protected by proprietary rights. Please check your credentials".
I can't imagine that there is herschel proprietary data still, given that the telescope hasn't taken data in years, so I am guessing something else is going on, but have sent a herschel helpdesk message to see if I can't get a definitive answer on that.
I tried a "try except" around the call to say don't grab those observation_id that appear to be proprietary, but python won't let me do an except LoginError. It tells me "NameError: name 'LoginError' is not defined". (and I tried, but it doesn't work to 'except NameError')
Is it possible for astroquery to throw some other, recognizable error, so I can move around this problem? I'll take other suggested workarounds!
from astroquery.esa.hsa import HSA
test_table = HSA.query_hsa_tap("select top 10 observation_id from hsa.v_active_observation where "
"contains(point('ICRS', hsa.v_active_observation.ra, hsa.v_active_observation.dec), "
"circle('ICRS', 100.2417,9.895, 1.1))=1")
for row in test_table:
print(str(row['observation_id']) ) #confirm that syntax is not the problem
try:
HSA.download_data(observation_id=str(row['observation_id']), retrieval_type='OBSERVATION',
instrument_name='PACS', download_dir = 'data/herschel')
except LoginError:
#there is some problem here with the observation_id which causes Herschel to think it is proprietary
#we just won't get this data, move on to the next observation
print("loginerror")

I'm not yet labelling it as a bug, as astroquery may very well hit something on the server side that returns the proprietary response.
I'll follow-up directly with Jessica about point no2, the immediate workarounds and importing the errors problem, so we should keep only the parts affecting astroquery and HSA in this issue.
Regarding this issue, I think the error is misleading. I have been checking and the same commands are failing due to an observation that is associated to a different instrument (not PACS). To fix this, you can modify your initial query to the following one:
select top 10 observation_id from hsa.v_active_observation join hsa.instrument using (instrument_oid) where contains(point('ICRS', hsa.v_active_observation.ra, hsa.v_active_observation.dec), circle('ICRS', 100.2417,9.895, 1.1))=1 and hsa.instrument.instrument_name='PACS'.

Thanks,
minimum example, using the coords and syntax for query_hsa_tap that are listed in the astroquery readthedocs page (https://astroquery.readthedocs.io/en/latest/esa/hsa/hsa.html):
