  We present the complete data set, model and line identification of a survey
of the emission from the C-rich protoplanetary nebula CRL 618 performed with
the IRAM-30m telescope in the following frequency ranges: 80.25-115.75 GHz,
131.25-179.25 GHz, and 204.25-275.250 GHz. A selection of lines from different
species has been used in previous works to derive the structure of the source,
its physical conditions and the chemical abundances in the different gas
regions. In this work, we have used this information to run a global simulation
of the spectrum in order to check the consistency of the model and to ease the
task of line identification. The total number of lines that have a
correspondence in both data and model is ~3100, although quite often in this
object many lines blend into complex features so that the model, that takes
into account line blending, is a key tool at this stage of the analysis. Of all
the lines that we have been able to label, ~55% of them belong to the different
forms of HC3N, and ~18% to those of HC5N. The density of remaining unidentified
features above the 3sigma limit is only one per ~2.1 GHz (74 features), which
is unprecedented in the analysis of this type of large millimeter-wave line
surveys.
