Details on planets and asteroids

Mars and Uranus are well known primary calibrators for photometric calibration and for beam maps. Jupiter, Saturn can be used for the errorbeams or to map the satellites.

Rough fluxes

The following table gives only rough numbers for the fluxes. Note that some are strongly varying in R.A./Dec, distance, flux and brightness temperature.

Name	Right Ascension	Declination	Diam (arcsec)	Flux @ 1.15 mm Jy	Flux @ 2.00 mm	TB K
MERCURY	12:04:33.0985	00:13:18.988	8.25x8.25	1156.5	387.2	450
MARS	10:46:24.9914	09:12:15.947	4.00x3.98	117.08	39.50	198
JUPITER	10:57:47.6613	07:38:57.99	31.77x29.71	5928.86	2004.54	170
SATURN	16:00:29.2947	-18:50:13.907	15.49x13.83	1181.45	400.29	150
URANUS	01:09:34.4370	06:39:29.520	3.69x3.58	44.01	18.44	93 @1mm, 113 @2mm
NEPTUNE	22:37:43.8247	-09:32:13.503	2.30x2.24	17.16	7.19	93 @1mm, 113 @2mm (yes, same as Uranus)

Accurate fluxes

For accurate fluxes, use the following predictions from recent planetary models:

For Uranus and Neptune:
- Download the ESA2 templates of the model of Moreno 2010 ("Neptune and Uranus planetary brightness temperature tabulation. Technical report, ESA Herschel Science Center).
- Download the ESA4 templates of the models of Moreno and Orton described by Bendo et al. 2013 (Flux calibration of the Herschel-SPIRE photometer, MNRAS 433, 3062, 2013).
For Mars:
- Visit the web page of Emmanuel Lelloche. It will ask for the HPBW at 300 GHz which is ~8" at the 30m.

For asteroids, please check the information compiled here on the Pointing sources and calibrators wiki page by IH.

Interface with the telescope: Pako

- 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.
