List of Astronomical Target
1. Planets and Asteroids
Mars, Uranus, Neptune for photometric calibration (primary calibrators) and beam maps.
Jupiter, Saturn can be used for the sidelobes only or to map the satellites

Here are the ephemerides for all planets The near and far sidelobes could be measured with Jupiter and Saturn.
2. Usual bright quasars, secondary calibrators and strong galactic sources (end of the list is dedicated to polarisation) for image quality, linearity checks, and pointing sessions: Bright source selection.
In addition to that, check the Pointing sources and calibrators wiki page by IH.
3. Weak Galactic sources for photometric calibration: weak galactic sources.
Here is the full detailed formatted list Full list with some fluxes.
Here is the catalog for Pako has to be RENAMED to NIKA2R1.sou on the pako computer.
Interface with the telescope: Pako
Short manual on useful "Pako for Nika" see on Granada computers on the NIKA directory Pako_helpv??.txt ??? OR IS THERE NOW A PAKO WIKI ???
- Pako scripts are in the Pako subdirectory
- Before starting the pointing session, we may be requested to move the azimuth by 60deg to reset the inclinometer of the az axis.
- Always stay at more that 1 deg from the Sun. There are internal safeties that prevent the antenna to point to the Sun, but we may not get error messages.
- The antenna can point between 60 and 460 degrees in azimuth, between 20 and 80 degrees in elevation.
- If a source is available both at low and high azimuth, use command SET TOPO LOW (or SET TOPO HIGH) to stay on the source without moving.
- The minimum number of sources to observe for the pointing model is 15. 30 is good enough.
- the pointing sources should be observed on 'short' period, e.g. 3-4 hours to avoid daily pointing variations.
