 .Arrays status tonight: 126 pixels 2mm - good noise; 8 pixels 1mm noise should be good (reduce the number of pixels so that total tones power below amplifier saturation).  .Arrays status tonight: (126 pixels 2mm, 90 pixels 1.25mm):


Plan for tonight (126 pixels 2mm, 90 pixels 1.25mm)

Pointing model was updated by Juan Penalver:
 .use 31 pointing values obtained yesterday
 .dispersion goes from 2.8 to 2.5 arcsec.
 . DeltaP1=-3.46+-0.72
 . DeltaP7=+1.88+-0.44

ATTENTION: Juan's model has been calculated using the relative pointing offsets measured during the pointing session thinking these was absolute offset. For example the 1st cross relative offsets are (-1.33;1.36) but the absolute ones are (8.47-1.33;11.09+1.36). Tomorrow Juan will implement a new pointing model based on the correct offsets. Note this misunderstanding explain why we found big offsets today on the pointings instead of values ~< 2 arcsec.

ATTENTION: At the beginning of the session we forgot to change the reference pixel (when we point a source it is centered on that pixel); so we used the pixel 454 of the 2mm array, but it has no 1mm counterpart, so none of the 1mm array pointing are usable ! Don' t forget to change the reference tomorrow; choose either pixel 432 of the 1mm array or pixel 33 of the 1mm array which are close to each other on the sky, or, pixel 414 of the 2mm array or pixel 8 of the 1mm array which are also close to each other on the sky, and in all cases they are all quite close from the center of the arrays.

 .Quick description of the session: Proceed with the observing procedures (see [[ListOfAstroTarget2012N5]]): geom, pointing cross, focus, etc. (e.g.check plateau on strong sources) then fainter and fainter sources to check sensitivity.  .Quick description of the session: see .[[http://www.iram.es/IRAMES/mainWiki/DailyReports5#Monday_19.2BAC8-11|Daily Report]]

NIKA November 2012 S5

Back to list of day to day logbook of observations

2012-11-19

  • Cryostat Temperature: 150 +/- 0.02 mK (regulated with power 50uW)
  • Arrays status tonight: (126 pixels 2mm, 90 pixels 1.25mm):

Plan for tonight (126 pixels 2mm, 90 pixels 1.25mm)

Pointing model was updated by Juan Penalver:

  • use 31 pointing values obtained yesterday
  • dispersion goes from 2.8 to 2.5 arcsec.

  • DeltaP1=-3.46+-0.72

  • DeltaP7=+1.88+-0.44

ATTENTION: Juan's model has been calculated using the relative pointing offsets measured during the pointing session thinking these was absolute offset. For example the 1st cross relative offsets are (-1.33;1.36) but the absolute ones are (8.47-1.33;11.09+1.36). Tomorrow Juan will implement a new pointing model based on the correct offsets. Note this misunderstanding explain why we found big offsets today on the pointings instead of values ~< 2 arcsec.

ATTENTION: At the beginning of the session we forgot to change the reference pixel (when we point a source it is centered on that pixel); so we used the pixel 454 of the 2mm array, but it has no 1mm counterpart, so none of the 1mm array pointing are usable ! Don' t forget to change the reference tomorrow; choose either pixel 432 of the 1mm array or pixel 33 of the 1mm array which are close to each other on the sky, or, pixel 414 of the 2mm array or pixel 8 of the 1mm array which are also close to each other on the sky, and in all cases they are all quite close from the center of the arrays.
