=== 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 from Gildas, FXD ====

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.

==== Accurate fluxes ====

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

 * For Uranus and Neptune:

  * Download the [[ ftp://ftp.sciops.esa.int/pub/hsc-calibration/PlanetaryModels/ESA2 | ESA2 templates ]] of the model of Moreno 2010 ("Neptune and Uranus planetary brightness temperature tabulation. Technical report, ESA Herschel Science Center). 
  * Download the [[ ftp://ftp.sciops.esa.int/pub/hsc-calibration/PlanetaryModels/ESA4/ | ESA4 templates ]] of the models of Moreno and Orton described by  Bendo et al. 2013 ([[http://adsabs.harvard.edu/abs/2013MNRAS.433.3062B | Flux calibration of the Herschel-SPIRE photometer]], MNRAS 433, 3062, 2013).

 * For Mars:

  * Visit the [[ http://www.lesia.obspm.fr/perso/emmanuel-lellouch/mars/ | 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 [[http://www.iram.es/IRAMES/mainWiki/Continuum/Calibrators|Pointing sources and calibrators wiki page by IH]].

== Interface with the telescope: Pako ==

Short manual on useful "Pako for Nika" see on Granada computers on the NIKA directory Pako_helpv??.txt ==> Obsolete. Has been replaced by much simpler procedures listed on the control computers screen wallpaper:

[[attachment:NIKA2_Wallpaper.PNG]] 

- 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.

== Commissioning requirements and observations plan ==

see the [[http://www.iram.fr/wiki/nika2/index.php/CommissioningNIKA2#Detailed_plan|private wiki]]

== Focus session ==

See L. Perotto J.F Lestrade  for more information

=== Preparation ===

 1. Source = Uranus (QSO of a few Janskies OK)
 2. Do a pointing
 3. Check proper Z,X,Y focus at the center of the array

=== Session Focus z across the FoV ===

==== first focus at the centre of the array ====

{{{
offset -24.5 3.4 /sys nasmyth

@focusOTF
}}}

 *enter 0 as the central focus z value
 *proceed to the RTA
 *reduce the scans with : 

{{{
nk_rta, '20160312s1', /nas, /xyguess, /largemap, rmax_keep=30, radius=35, /nopng
}}}

When the 5 scans are done :
{{{
nk_focus_liss_old, '20160312s'+strtrim([1,2,3,4,5], 2), /nas, /xyguess, rmax_keep=30, get_focus_error=1, imzoom=1
}}}

 * read the optimal z focus
 * if dz > 0.3 ou dz < -0.3 redo @focusOTF  with the actual optimal z focus

==== focus away from the centre (18 points) ====

 * P1 a P7 : 1st diagonal  ( \ )
 * Q1 a Q6 : 2nd diagonal ( / )
 * C1 a C4 : circle
