Function:     irim_getpars

Purpose:      read destripe parameters from irds at (snip,sdet)

Category:     IRAS

Author:       Do Kester		

Use:  
int irim_getpars( 
	fchar		irds,	  IN: name of irds
	fint		snip,     IN: sequential snip numbers
	fint		sdet,	  IN: sequential detector number
	float		*cal,     OU: parameters; BASE, DRIFT, GAIN
	fint		nc,       IN: maximum allowable number of params
	float		*scale )  OU: stddev pertaining to this fit

returns: >= 0 : number of destripe parameters found 
	 -1   : no parameters present where they should be.

Comment:      This routine is not callable in Fortran
