Description
imrot
is a utility for rotating and/or reflecting FITS or IRAF images. Images can

a different data type than that in which it is input, and IRAF files may be
written out as FITS files.

-f
Write FITS image from IRAF input
-l
Reflect image across vertical axis
-o
Allow overwriting of input image, else write new one
-r <angle>
Image rotation angle in degrees (default 0)
-s

-v
Verbose
-x <num>
Output pixel size in bits (FITS code, default=input)
Allowed values are 8, 16, 32 for integers, -16 for unsigned integers, and
-32 and -64 for 4- and 8-byte floating point numbers
