• Jan-Willem Steeb
• Joshua Hoskins
• Joshua Marvil
• Victor de Souza Magalhaes
• Srikrishna Sekhar

Development

Josh H.

Done:

• Factorization
• Move dependencies to graphviper

on going:

• New tests
  • Combine
  • Core

Srikrishna

Done:

• Forked astrohack to his own repository
• Created prototype of zernicke fitter

Ongoing:

• Adapting zernicke fitting code to work on apertures rather than beams.

Victor

Done:

• Time smoothing of visibilities and pointing.
• Code review of dev branch.

On going:

• ALMA Near field holography:
  • New ASDM bindings are now able to open ALMA near field holographies
  • We probably will need to write our own filler, the form will be:
    • ASDM -> holog.zarr (i.e. skipping extract_holog)
  • After we have an acessible file, we will need to model the near field effects

Todo:

• Reading of near field ALMA ASDM to .holog.zarr.
• Check combine with weights.
• Check data on the panel OTF blind test.

Validation

What validated OTF looks like?

• OTF mode is validated.

What Astrohack validated looks like?

• ONGOING Aperture image quality measured quantitavely.
• TODO Panels matching within 15 mils from the blind test.
• TODO Optical misaligment fitting values.
• TODO Check fully sampled short dump time holographies.
• TODO Check corrections for Antenna 16 damaged panel.

Pedro

• Blind test with panels
  • Close to detection limits.
  • astrohack.panel did not detect displacements as well as AIPS.

Locit test date

• At the next antenna move in about a month.

Next Meeting

• April First 2024.
