`SORTRF` : Sort/merge reflection data

label	information added to logical record labl of the bdf
merge	items on input bdf to be averaged

SORTRF	Option	Code	Arg		Def
	sorting order	`ord`	`hkl`	slow/med/fast indices	`hkl`
	sorting type	`sort`	`n`	`1` -high $\rightarrow$ 0 $\rightarrow$ +high index
				`2` as `1`with Friedels adjacent
				`3` as `1`with \|h\|=\|k\|=\|l\| groups
	equivalent hkl data	`nav`		do not average equivalent hkl
		`clus`		cluster equivalent hkl
		`aver`	`n`	`1` standard average
				`2` Fisher test average
	rcode threshold	`rthr`	`r`	rcode=2 if `r` $\sigma$ Y>Y	`r=0`
	prior rcode values	`ignore`		do not use input rcodes	`use`
	culling for average 1	`ncull`		no culling
		`cull`	`t`	cull Y if \|Y-Y\|> `t` $\sigma$ Y	`3`
	Friedel independence ^[a]	`pakfrl`		pack pairs in single packet ^[b]
		`sepfrl`		keep pairs as separate reflns ^[c]
	averaged coefficients ^[d]	`irel`		average I and $\sigma$ I
		`f2rl`		average $\|F^{2}\|$ and $\sigma$ $\|F^{2}\|$
		`frel`		average $\|F\|$ and $\sigma$ $\|F\|$
	print output data	`print`	`-n`	print `n` problem hkl's	`25`
		`print`	`n`	print `n` hkl
		`nopr`		do not print
	print observations	`mob`	`n`	print `n` `100`
	$\sigma$ 's for average 2	`success`	`n`	`1` Poisson
	if hypothesis true			`2` equivalents
				`3` maximum
	$\sigma$ 's for average 2	`unsucce`	`n`	`1` Poisson
	if hypothesis is false			`2` equivalents
				`3` maximum
				`4` reject reflection
	dataset number	`dset`	`n`		`1`
^[a]Friedel related data is treated as non-equivalent data if one of these options is entered. Otherwise, Friedel pairs are considered to be symmetrically equivalent. ^[b]Correct option if Friedel data is to be used in CRYLSQ for an `xabs` refinement. ^[c]Correct option if Friedel data is to be used in LSLS for a twinop refinement. ^[d]Only the specified coefficient type is merged. Other coefficients on the input bdf are not averaged, unless on a merge line. If the specified coefficient is not present on the bdf, the coefficients I, $F^{2}$ and F will be used in that order. I is the default.
