• Discussion of datasets in the repository (From Todd and Al)
  • New: 4 polarizations at Band 3 (parallactic angle: -16 to +88 deg)
  • NGC 7674 CO 3-2 (first uid with LO offsetting, second without; both include a Delay Calibration intent)
  • Two quasars at Band 6 (with and w/o LO offsetting) 0538-440, 0522-364 (no LOOffset)
  • 4 polarizations at Band 3 (J0538-440; parallactic angle = -48 to +78 deg )
  • Stellar Water Masers B9
  • Ceres
  • Baseline determination within SB
• Access to Tiger Team wiki.
• Site cloud camera: (availability of TMT test camera)CSV-421
• Flux Calibration using planets (Fomalont) CSV-549
  • Planets_ResolvedCals.txt: Using partially resolved calibrators
• Self calibration issues (Fomalont; see below)
• Early Science Configurations (see below)
• AOB

Self-Calibration

• CSV-618: "Self-Calibration: Observing, reduction and imaging" by Ed Fomalont. Please, have a look into this ticket if you want to learn about self-calibration.

ES Configurations

• There are two candidates for Early Science configurations under study.
  • Compact configuration
    • alma16ant.pdf: F. Boone discussion on design of prospective ES compact array
    • Compact_16.csv: Strawman compact 16 antenna configuration from F. Boone (see writeup)
    • Compact_16_RItests.pdf: Remy simulations using strawman 16 element compact array.
  • 250m configuration
    • 250mArray_16_CSV.cfg: Strawman 250m ES array
