ABSTRACT
This program will observe PN VY22 at 3 different positions using the WFC3 IR G102 and G141 grisms. The data will be used to calculate
wavelength solutions for the grisms, and will be compared with those derived from programs 11937, 12355 and 12356 to monitor for potential time
evolution of the calibration.
OBSERVING DESCRIPTION
The PN Vy2-2 is observed as a wavelength calibrator at three different positions in the field though each of the G102 and G141 grisms. "Center,"
"Lower Center," and "Upper Center" are repeated from the 9-point pattern used in program 11937. As in previous calibration programs, each
dispersed exposure is preceeded by two direct images, to measure the source offsets between direct and dispersed modes, and establish the

wavelength zeropoint for each dispersed exposure. For G102 (G140) observations, the F098M and F105W (F140W and F160W) filters are used for
the accompanying direct exposures. The number of FPA readouts (nsamp) is minimized for each exposure in order to avoid as much visibility time
lost to buffer dumps as possible. POSTARGs are used to move the target to different locations in the field. POSTARGs are also used at the central
exposure of the pattern in order to shift the location of the first-order spectrum so that it is near the center of the FOV.
