Instruction for Herc field, in directory Hect_May

Go through Herc_9 to Herc_16: if the blue side images are elongated to go back and repeat the number of spoiled exposures on the blue side, with only the blue side exposing so that it guides properly. It is more important that we get four or five pointings with a full complement of blue and red imaging than it is to get all of the pointings. Call Sand: 628-840-3588
