This describes the first public data release (DR1) of the Calar Alto Void Integral-field Treasury surveY (CAVITY), comprising
science-grade optical datacubes for the initial 100 out of a total of ∼ 300 galaxies in the Local Universe (0.005 < z < 0.050). These
data were acquired using the integral-field spectrograph PMAS/PPak mounted on the 3.5 m telescope at the Calar Alto observatory.
The DR1 galaxy sample encompasses diverse characteristics in color–magnitude space, morphological type, stellar mass, and gas
ionization conditions, providing a rich resource for addressing various inquiries in galaxy evolution through spatially resolved spectroscopy.
Galaxies were observed with the low-resolution V500 setup spanning the wavelength range 3745–7500 Å with a spectral resolution of 6.0 Å (FWHM).
We describe the characteristics and data structure of the CAVITY datasets essential for their scientific utilization, highlighting considerations
such as vignetting effects, identification of bad pixels, and management of spatially correlated noise.
