Rename it to NIKA2R1.sou to use it in Pako. === LST coverage (created with nika2.astro for 10-Mar-2016) === 1. Planets [[attachment:Planethorizon.pdf|planets]] 2. Strong Galactic sources [[attachment:StrongGalSources.pdf|Strong Gal. Sources]] 3. Strong pointing sources [[attachment:StrongPoiSources.pdf|Strong Pointing Sources]] 1. Radio sources from IRAM catalog [[attachment:nika2-radio.pdf|nika2-radio.pdf]]. 1. Planets, Asteroids, and Secondary Calibrators (from Lisenfeld+2000) [[attachment:nika2-secondaries.pdf|nika2-secondaries.pdf]] 1. Strong Galactic sources [[attachment:nika2-galactic.pdf|nika2-galactic.pdf]] 1. Weak Galactic sources [[attachment:nika2-weak-galactic.pdf|nika2-weak-galactic.pdf]] 1. Nearby galaxies [[attachment:nika2-nearby-galaxies.pdf|nika2-nearby-galaxies.pdf]] 1. Distant galaxies or faint quasars [[attachment:nika2-distant.pdf|nika2-distant.pdf]] === 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. ||Name ||Right Ascension||Declination||Diam (arcsec)||Flux @ 1.15 mm Jy||Flux @ 2.00 mm||TB K || ||MERCURY ||<)>22:43:41.7350 ||<)> -10:25:12.251 ||<)> 5.01x5.01 ||<)> 426.495 ||<)> 142.793 ||<)> 450 || ||VENUS ||<)>22:00:13.0011 ||<)> -13:17:06.886 ||<)> 10.88x10.88 ||<)> 2011.39 ||<)> 673.424 ||<)> 350 || ||MARS ||<)>15:58:45.0861 ||<)> -19:15:55.671 ||<)> 9.49x9.45 ||<)> 721.117 ||<)> 242.987 ||<)> 216.19 || ||JUPITER ||<)>11:18:21.4499 ||<)> 06:04:59.105 ||<)> 44.39x41.51 ||<)> ||<)> ||<)> 170 || ||SATURN ||<)>17:00:53.1914 ||<)> -21:00:24.540 ||<)> 16.71x14.91 ||<)> ||<)> ||<)> 150 || ||URANUS ||<)>01:10:09.4773 ||<)> 06:47:44.651 ||<)> 3.36x3.26 ||<)> 36.4466 ||<)> 15.2768 ||<)> 93 @1mm, 113 @2mm || ||NEPTUNE ||<)>22:46:56.5421 ||<)> -08:35:35.276 ||<)> 2.17x2.11 ||<)> 15.2350 ||<)> 6.38585 ||<)> 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 [[ 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.
