Data on light pollution.  Infos on http://lightmeter.astronomy2009.at, also
gwuchterl@tls-tautenburg.de should know more.

The data here gets uploaded through a special renderer (in bin) since auth is
done through the path.  You need a subdirectory upload writable by whoever the
server runs as (currently msdemlei).

To add a new station,

cd stations
cp ../template.kv <name>.kv
vi <name>.kv
# make up an access key as desired (e.g., use pwgen), leave calib* empty.
# Paste data from data providers above.
# type usually is IYA Lightmeter these days
# For now, east longitude  is positive (maybe change this?)
cd ..
gavo imp q stationsdata
# reply to the mail, giving the accessKey.  Here's a template:

"""
Your access key is ACCESS_KEY.  You can upload manually to
http://dc.g-vo.org/lightmeter/q/upload/custom/STATION_ID/ACCESS_KEY

For automated uploads, see

http://dc.g-vo.org/lightmeter/q/upload/info

To see what you've uploaded, go to

http://dc.g-vo.org/lightmeter/q/upload/static/STATION_ID

Once Günther Wuchterl has calibrated your lightmeter, the reduced data is
ingested into the database and can be queried using a form at

http://dc.g-vo.org/lightmeter/q/weather/form

or using ADQL at http://dc.g-vo.org/adql.

Feel free to contact us for any further questions, and in particular
if something doesn't work as expected.

Cheers,

Add a line to Contacts specifying the e-mail address for the station id.


-------------------------------

When a calibration comes in, the mail should give the parameters a, b, c,
and d for W/m^2.  Enter those values in the calibX fields of the stations .kv
file.

Then, in the lightmeter directory,

gavo imp q stationsdata  (this imports the new data into the database)

Optionally (but recommended, you can try to ingest the calibrated
data sets; this may take a while):

gavo imp q add (this should pick up data from the changed station)




-------------------------------

To recreate the whole thing (DON'T!  It's going to take ages!), do
gavo imp q createTables
gavo imp q stationsdata  (which reads .kv-files from stations)
gavo imp q add

When a calibration was wrong, you need to nuke the station's ingested data
and tell the machinery you did so.  So, for the id NL_Utrecht_2 this looks
like this:

delete from lightmeter.measurements where stationid='NL_Utrecht_2';
delete from lightmeter.filesindb where stationid='NL_Utrecht_2';

Then, correct the calibration, say ``gavo imp q stationsdata`` and
``gavo imp q``
