Data outside the survey area
There are tsObj files which have no or few primary objects
target version because they lie outside the
lambda limits in a number of stripes (they have been made primary in the
best version). As a consequence, querying the
target photometry catalogs for primary objects in this
part of the sky will not return any objects, although they do exist in
Here is the list of fields which have no or few
primary objects in
target in DR3.
Another thing to watch out for is that the mu limits in the
tsChunk*.par files will therefore extend beyond the survey lambda
limits. A consequence is that the mask csv's, which use these
mu limits, will extend beyond the lambda limits as well.
