WCPS_Only attach the selected bands when encode in netCDF

[Bang Pham Huu]

The error from Olly (PML), he wanted to do a WCPS query with select 1 band

for c in (V2_monthly_cci_uncert_combined_test_renamed)
return
encode
( 
(c[ansi("1998-01-01T00:00:00+00:00"), Lat(0.1:0.2), Long(10.0:10.1)].chlor_a > 25 )
 * 
c[ansi("1998-01-01T00:00:00+00:00"), Lat(0.1:0.2), Long(10.0:10.1)].chlor_a, "netcdf"
)

error in Rasql from the query

Petascope Error: Error evaluating rasdaman query:

so in the attached metadata, it should only use 1 band (e.g: chlor_a) not combine all these other bands (chlor_a_log10_bias, chlor_a_log10_rmsd) as will has error when encode in netCDF.

another working example for irr_cube_2 (which has 2 bands) so it need to specific 2 bands correctly, not just 1 band

rasql -q 'select encode ( c, "netcdf", "{ \"dimensions\": [\"Lat\", \"Long\"], \"variables\": { \"Lat\": {
\"type\":\"double\",\"data\":[0.1],\"metadata\":{},\"name\":\"Lat\"}, \"Long\": { \"type\":\"double\",\"data\":[10.0,10.0416666666667,10.0833333333334],\"metadata\":{},\"name\":\"Long\" },

Should be closed I guess?
