  We present the ancillary data and basic physical measurements for the
galaxies in the ALMA Large Program to Investigate C+ at Early Times (ALPINE)
survey - the first large multi-wavelength survey which aims at characterizing
the gas and dust properties of 118 main-sequence galaxies at redshifts 4.4 < z
< 5.9 via the measurement of [CII]-emission at 158 micro-meter (64% at
>3.5$\sigma$) and the surrounding far-infrared (FIR) continuum in conjunction
with a wealth of optical and near-infrared data. We outline in detail the
spectroscopic data and selection of the galaxies as well as the ground- and
space-based imaging products. In addition, we provide several basic
measurements including stellar masses, star formation rates (SFR), rest-frame
ultra-violet (UV) luminosities, UV continuum slopes ($\beta$), and absorption
line redshifts, as well as H-alpha emission derived from Spitzer colors. We
find that the ALPINE sample is representative of the 4 < z < 6 galaxy
population selected by photometric methods and only slightly biased towards
bluer colors ($\Delta\beta$ ~ 0.2). Using [CII] as tracer of the systemic
redshift (confirmed for one galaxy at z=4.5 out of 118 for which we obtained
optical [OII]$\lambda$3727A emission), we confirm red shifted Ly-alpha emission
and blue shifted absorption lines similar to findings at lower redshifts. By
stacking the rest-frame UV spectra in the [CII] rest-frame we find that the
absorption lines in galaxies with high specific SFR are more blue shifted,
which could be indicative of stronger winds and outflows.
