- | * The new gain curve (Feb 2007) was corrected for opacity. | ||
* If no other information about the opacity is available a typical zenith tau value of about 0.02 should do a good job. | * If no other information about the opacity is available a typical zenith tau value of about 0.02 should do a good job. | ||
