π NAME π
okay so bestie, meet imua2 β she's here to Find USNO-A2.0 stars in FITS or IRAF image files. that's the whole assignment. no notes. π«
πΈ SYNOPSIS πΈ
imua2 [options] FITS or IRAF file(s)
π¦ DESCRIPTION π¦
so here's what she actually does: she searches the USNO-A2.0 Catalog inside the area that the world coordinate system in an image header describes. πβ¨
and the plot twist you need to know β imua2 is not her own separate executable. she is a link to imcat. same girl, different name on the door, iykyk. π

okay that's the whole page, you ate it, you understood it, periodt. π π¦
this one's from the WCS era, dated 14 April 1998, living under the manual name imua2(1) β so go forth and find those USNO-A2.0 stars, bestie, she's rooting for you π«Άβ¨
