Guider Algorithm Status

No.	Algorithm	K1 Status	K2 Status
0	"Original" Marginal Centroid	OK	OK
1	2-D Gaussian Fit	N/A	N/A
2	Marginal Centroid (Optimal Box)	OK*	OK*
3	Marginal Centroid (Fixed Box)	Out of order	Out of order
4		N/A	N/A
5		N/A	N/A
6		N/A	N/A

Notes

• Algo 2 should only be used for slitless guiding.
• Algo 3 should not be used at present.
