When I perform psf of daophot on just one image and I choose interactive "yes", I can pick the psf stars by myself but when I perform it on multiple images and choose interactive "no", it picks the 5 brightest psf stars automatically from image.mag.1. When I perform psf on multiple images, can iraf pick exactly the same 5 stars I choose on every image but not choosing the brightest ones automatically?Here is the parameters I use.image = @images.lis Input image(s) for which to build PSF
photfile= @mag.lis Input photometry file(s) (default: image.mag.?)
pstfile = @pst.lis Input psf star list(s) (default: image.pst?)
psfimage= default Output PSF image(s) (default: image.psf.?)
opstfile= default Output PSF star list(s) (default:image.pst.?)
groupfil= default Output PSF star group file(s) (default: image.ps
(plotfil= ) Output plot metacode file
(datapar= ) Data dependent parameters
(daopars= ) Psf fitting parameters
(matchby= yes) Match psf star list to photometry file(s) by id
(interac= no) Compute the psf interactively ?
(mkstars= no) Mark deleted and accepted psf stars ?
(showplo= yes) Show plots of PSF stars ?
(plottyp= mesh) Default plot type (mesh|contour|radial)
(icomman= ) Image cursor: [x y wcs] key [cmd]
(gcomman= ) Graphics cursor: [x y wcs] key [cmd]
(wcsin = )_.wcsin) The input coordinate system (logical,tv,physical
