[ImageDM ] dataset datatype diagram comments

[Louys Mireille]

Hi Mark , all ,

the Obscore Spec 
http://www.ivoa.net/documents/ObsCore/20111028/REC-ObsCore-v1.0-20111028.pdf
defines : image, cube, spectrum, SED, timeseries, visibility, event.

it clearly states that a light curve is  considered as a kind of 
Timeseries;
see section   3.3.1. Data Product Type

Sorry for the confusion.
