The agreement is as good as could be expected for bright images. No. 23 gives poor images, but the reading 7.7 for the fourth exposure on page 10 is certainly wrong, possibly an error of a unit of the scale. Reject.
No. [[strikethrough]]20[[/strikethrough]]19 appears to have been measured too bright for the fourth exposure on page 10. Reject.
The bright images do not compare well with scale.
