Interface with the telescope: Pako

Short manual on useful "Pako for Nika" see on Granada computers 2013_docs_for_observations/Pako_helpv15.txt

- 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.

- try to get sources uniformly distributed on the sky, hence give priority to high elevation sources that are usually harder to reach.

- Do one focus at the beginning. No need to do more focus than one every 2-3hours.

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

Abstract

We can consider using 40 hours to test, calibrate and commission the instrument. Procedures will be tested several times, which include Pointing (Cross), Focus, OTF_Geometry, Skydip, Lissajous, OTF_Map. Tests include tuning, auto-tuning, robustness of data acquisition. Photometric calibration includes planets and secondary calibrators. Skydip and Lissajous sequences need to be better tested than before. Other sequences should be straightforward. The plateau systematics will be investigated via the OTG_geometry sequences. Near sidelobes can be measured by doing 5x5 map of of Jupiter or Saturn and use Pf variable.

Science case demonstration

We want to show typical science demonstration data in five areas where we can compare our results with previous (Mambo, Laboca, JCMT, Bolocam) bolometer array results. We have a total of 85 hours. About 12 hours for 7 days. We dedicate 40 hours for commissioning, 45 hours are left for 5 scientific programs (Rho Oph, M33, HSO extragalactic sources, Deep survey and RXJ). Taking out 15 hours for calibration (calibration on planets and secondary calibrators, pointing, focus, skydip), we are left with 30 hours of science scans. The sources to be used during commissioning and science are the same.

  1. Rho Oph (6h)
  2. Extended galaxies (8h) M33
  3. Faint sources (7h)
  4. Deep survey (4h)
  5. Clusters of galaxies (5h) RXJ

Here is a priority list of targets (see the complete list above) for commissioning and science observations.

  1. Galactic regions, From brighter to fainter TBD
    • 1.1. Large map of OrionLBS23SM 1.2. Large map of DR21 1.3. Large map of Crab, CasA 1.4. Map of NGC2023 1.5. Map of the horsehead
  2. Galactic faint sources: Rho Oph
  3. Extended galaxies
    • 2.1. M82 2.2. M33 2.3. NGC891
  4. Faint high-z point sources starting with 30 mJy sources at 1mm TBD:
    • Arp220, 4C05.19, APM08279+5255, MM18423, SMMJ2135, HAT133008, , HAT133649, HAT141351 H1413+517, F10214+4724, HLSW01, BR1202-0725, BRI1335-0417, SBS1408+567, , HSO_ID017, HSO_ID081, HSO_ID011,HSO_ID130.

HATLENS01, HATLENS02, HATLENS03 (=HAT114637), HATLENS04, HATLENS05 (=HSO_ID141), HATLENS06 (=HAT134429), HATLENS07 (=HAT083051), HATLENS08, HATLENS09 (=HAT113526)

  1. Deep survey: The idea is to cover a field with 1mJy rms sensitivity at 1mm and 0.5mJy at 2mm, this is about one hour per camera FOV (about 3 arcmin^2). Map should be 3x4 arcmin. Exact field to be decided around a faint source (5-10 mJy)
  2. Clusters of galaxies RXJ1347-1145, Confirm
