README

        

Adding the "userradii" facility changes the following files:

    analyse.c   -- changed to call the "userradii" function

    catout.c    -- changed to initialise obj.rad FLAGs

    userradii.c -- the code for doing the calculations

    define.h    -- changed to define number of radii (NRAD)

    userradii.h -- defines prototype for userradii call

    param.h     -- added RAD0 through RAD15 catalogue parameters

    types.h     -- added rad member to objstruct and rad_type,

                   nrad_type, rad and nrad to prefstruct.

    prefs.h     -- added RAD_THRESH and RAD_TYPE parameters

Note: could make analysis more efficient by pre-calculating the

thresholds somewhere just once, rather for each object.

Adding NDF origin parameter X_PIXEL and Y_PIXEL makes modifications 

in:

    readimage.c -- get the NDF origins

    

    analyse.c   -- set the X_PIXEL and Y_PIXEL values

    param.h     -- added X_PIXEL and Y_PIXEL 

    types.h     -- added ndfposx, ndfposy and origin[2].
