Abstract:
We present a catalogue of ALMA flux density measurements of 754
calibrators, obtained during the majority of the ALMA science
observations between 2012 August and 2017 September, for a total of
16263 observations in different bands and epochs. The flux densities
were measured by reprocessing the ALMA images generated in the
framework of the ALMACAL project, with a new code developed by the
Italian node of the European ALMA Regional Centre. A search in the
online data bases yielded redshift measurements for 589 sources (about
78 per cent of the total). Almost all sources are flat spectrum, based
on their low-frequency spectral index, and have properties consistent
with being blazars of different types.
Description:
The 754 calibrators were observed by ALMA between 2012 August and 2017
September. In total, we collected 16263 observations. The number of
observations in the different ALMA bands are: 5100 in band 3
(84-116GHz), 639 in band 4 (125-163GHz), 6319 in band 6 (211-275GHz),
3584 in band 7 (275-373GHz), 393 in band 8 (385-500GHz), 220 in band 9
(602-720GHz) and 8 in band 10 (787-950GHz). The catalogue gives the
ALMA name, the source classification, its redshift (if available), the
equatorial coordinates (RA and DEC; J2000), the flux density measured
in each observation with its error, the ALMA band in which the
observation was made, the effective observing frequency, and the date
and UTC time of the observation.

Note (2): This uncertainty is given by summing in quadrature the rms and a
typical ALMA calibration error equal to 5% of the flux (see paper).
Note (3): Band as follows:
3 = 84-116GHz
4 = 125-163GHz
6 = 211-275GHz
7 = 275-373GHz
8 = 385-500GHz
9 = 602-720GHz
10 = 787-950GHz

Global notes:
Note (G1): Classification as derived in the paper as follows:
1 = FSRQ
2 = BL Lac
3 = BL Lac-galaxy dominated
4 = Blazar uncertain type
5 = BL Lac candidate
6 = steep-spectrum
7 = uncertain
