Point-Source Scripts

FOCUS00

TEST: FOCUS00

Focus analysis script

Tasks:

  • Select exposures, get file names, get metadata (commandig, HK).

  • Check quality of data (integrated fluxes are roughly constant, matching expected level).

  • Subtract offset level.

  • Divide by Flat-field.

  • Crop stamps of the sources on each CCD/Quadrant.

    • save snapshot figures of sources.

  • for each source (5 x Nquadrants):

    • measure shape using Gaussian Fit

  • Find position of mirror that minimizes PSF sizes

  • Produce synoptic figures:

    source size and ellipticity across combined FOV (of 3 CCDs)

  • Save results.

PSF0X

TEST: PSF0X

PSF vs. Fluence, and Wavelength

PSF01 - nominal temperature PSF02 - alternative temperatures

Tasks:

  • Select exposures, get file names, get metadata (commandig, HK).

  • Check exposure time pattern matches test design.

  • Check quality of data (rough scaling of fluences with Exposure times).

  • Subtract offset level.

  • Divide by Flat-field.

  • Crop stamps of the sources on each CCD/Quadrant.

    • save snapshot figures of sources.

  • for each source:

    • measure shape using weighted moments

    • measure shape using Gaussian Fit

    • Bayesian Forward Modelling the optomechanic+detector PSF

  • Produce synoptic figures.

  • Save results.
