"Products are", not "product are."
The primary data product ofWMAP are sets of calibrated sky
maps at five frequency bands centered at 23 GHz (K band),
33 GHz (Ka band), 41 GHz (Q band), 61 GHz (V band),
and 94 GHz (W band), including measured noise levels and
beam transfer functions that describe the smoothing of the
sky signal resulting from the beam geometries. These maps
are provided for Stokes I , Q, and U parameters on a year-by-
year basis and in a year co-added format, and at several pixel
resolutions appropriate for various analyses. Changes relative to
the previous data release include the inclusion of seven years of
observational data, a new masking procedure that simplifies the
map-making process, and improvements of the beam maps and
window functions. Details of the processing used to generate
these products are described in the remainder of this work.

I'd say not necessarily. There is only one "primary data product" - the sets of maps. Other data products are not the primary product.
Maybe: "The primary data product of WMAP is a set of calibrated sky maps ... "
