Sensitivity of AOS algorithm to centroid offset

    XMLWordPrintable

    Details

      Description

      Investigate the sensitivity of AOS algorithm to centroid offset, i.e. the centroid information being inaccurate. Find out how shifting the centroid information provided to the algorithm affects the Zernike estimate. Describe with an appropriate metric.

            Investigation of the influence of varying the value of centroid attached to the donut stamp on the retrieved zernikes https://github.com/suberlak/AOS/blob/main/AOS_DM-33104_masks_centroid.ipynb . In summary it is a very small contribution because the image centroid is found in `ts_wep`, and `centroid` value is used to find the `field_XY` which is used to slightly shift the image radially in `image_cocenter`

            Since work on this ticket first turned to investigating centroid offsets https://github.com/lsst-sitcom/sitcomtn-044/tree/tickets/DM-33104 , I can either edit this ticket to be something like "Investigate the impact of centroid accuracy on Zernike retrieval", or make a new ticket and rename the branches I used for that PR to the SITCOMTN-044 https://sitcomtn-044.lsst.io/v/DM-33104/index.html .
