Need help relating RGZ To FIRST, NVSS, SDSS , WISE data

  • Tobend by Tobend

    Is there a post where the relationship between the RGZ image frame (size, orientation, centration) relative to those mentioned above is clearly summarised? Thanks in advance for any help or comments.

    What is the scale of the images? And the typical size of point sources (PSFs)? is a start.

    SDSS images have variable scale; you can see it if you tick the "Label" box in the left-hand panel, and the scale changed by clicking on a bar in the scale tool (below the Search button).

    FIRST images come with an image size (in pix) and labelled axes.

    There's a post somewhere with a mention of the NVSS scale, but I don't know where.

    WISE?
