The primary object of the study is to investigate the color line_4: and morphological evolution of cluster galaxies. Sufficient signal-to-noise line_5: will be obtained for all objects to see spiral structure, if present, and all line_6: fields contain starburst galaxies, whose morphology is of special interest. line_7: In addition, the data will yield structural parameters for the bright cluster line_8: galaxiess, which will aid in interpreting the classical Hubble diagram for line_9: the determination of the deceleration parameter. ! ! end of abstract general_form_proposers: lname: WESTPHAL fname: JAMES title: PROF. mi: A. inst: CALTECH country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: The observations consist of imaging a set of distant clusters in two line_2: colors (except the most distant cluster, for which the rest 4500 line_3: angstrom filter corresponds to a passband beyond the red limit of our line_4: instrument), with total exposures calculated to give comparable line_5: signal-to-noise for all objects. Positions for two of the clusters line_6: are still approximate and need to be verified with GASP, but all line_7: orientations are final. We still need to decide whether to dither line_8: the pointings slightly on the multiple exposures. ! question: 6 section: 1 line_1: All the exposures are specified as non-interruptible. No separate CR line_2: splits are called out because of the multiple exposures. ! question: 13 section: 1 line_1: Three distant cluster will be studied using multicolor imaging to investigate line_2: morphological and photometric evolution of galaxies and clusters. The data will line_3: also be used to perform classical photometric and angular-diameter cosmological line_4: tests. The redshift range covers clusters from 0.72 to 0.92. The clusters line_5: are: 1322+3115, 1322+3027, and 1603+4313. ! !end of general form text general_form_address: lname: FABER fname: SANDRA mi: M. category: CON inst: UC SANTA CRUZ - LICK OBSERVATORY addr_1: NATURAL SCIENCES II city: SANTA CRUZ state: CA zip: 95064 country: USA phone: 408-459-2944 ! lname: WESTPHAL fname: JAMES mi: A. title: PROF. category: PI inst: CALTECH addr_1: M/S 170-25 addr_2: DIVISION OF GEOLOGICAL addr_3: & PLANETARY SCIENCES city: PASADENA state: CA zip: 91125 country: USA phone: 818-395-4900 ! lname: LAUER fname: TOD mi: R. category: CON inst: NOAO addr_1: PO BOX 26732 city: TUCSON state: AZ zip: 85726 country: USA phone: 602-327-5511 ! lname: BAUM fname: WILLIAM category: CON inst: UNIV.
