abstract:

    line_1:        Multicolor photometry and spectroscopic redshifts are available for
    line_2:        a complete sample of faint galaxies in the southern cluster
    line_3:        Abell 370 at a redshift of z=0.37. Strong evidence has been found
    line_4:        for residual star formation in the red cluster galaxies. This may
    line_5:        reflect general evolution in the cluster ellipticals, or it could
    line_6:        represent the final transition from infalling gas-rich systems to
    line_7:        present-day lenticular galaxies. WFPC2 will be used to extend the
    line_8:        spectral energy distributions for cluster members into the UV
    line_9:        providing direct measures of the proportions of young and evolved
    line_10:       stars in a carefully selected sample of red members complete to
    line_11:       K=17.0.

  question:        3
    section:       1
    line_1:        We aim to obtain exposures of each of selected early-type cluster
    line_2:        members through the filters F255W and F336W.
    line_3:        
    line_4:        Our implementation preferences are as follows:
    line_5:        
    line_6:        First preference:
    line_7:        Our first preference is that all exposures in this program be taken 
    line_8:        together NO GAP, using the same guide stars, and maintaining the 
    line_9:        SAME ORIENT. Doing the observations NO GAP and using the same guide
    line_10:       stars will allow us to ensure the accuracy of the small POS TARG
    line_11:       offsets we are doing, and will also help in maintaining the SAME
    line_12:       ORIENT. If we are photon-starved, we could thus very reliably 
    line_13:       register and co-add all the frames in all the filters together if
    line_14:       need be.
    line_15:       
    line_16:       Second preference:
    line_17:       Our second preference is that Exposure Log lines 1-5 and 6-12
    line_18:       each be done NO GAP and still using the SAME ORIENT and same guide
    line_19:       stars for ALL exposures, 1-12. The two groups of exposures should
    line_20:       be done within a week's period so that the requirements of using 
    line_21:       the same guide stars and keeping the SAME ORIENT are more readily
    line_22:       preserved, and the calibration should be very similar, minimizing
    line_23:       any temporal variations as much as possible. The "WITHIN 7 DAYS"

!

  question:        3
    section:       2
    line_1:        requirement may be relaxed if necessary for scheduling, but we 
    line_2:        prefer it to remain so that all the exposures are done within the
    line_3:        amount of time necessary to maintain the SAME ORIENT and the use 
    line_4:        of the same guide stars. Again, if we are photon-starved, we can 
    line_5:        at least preserve the registration of pointing and offsets for 
    line_6:        all exposures. We can co-add the frames in the two filters at 
    line_7:        least, and may still be able to co-add all of the exposures 
    line_8:        ( 1-12 ) very well if the same guide stars and SAME ORIENT are 
    line_9:        still used for 1-12. Breaking the exposures into two separate 
    line_10:       sub-groups ( 1-5 and 6-12 ) allows a break for SAA passages, etc. 
    line_11:       if needed.
    line_12:
    line_13:       Absolute ORIENT angle preferences:
    line_14:       The absolute ORIENT=255D +/- 30D may be changed if needed for 
    line_15:       scheduling, but we request that we be consulted on any change so 
    line_16:       that we can help pick the next best alternate ORIENT angles to 
    line_17:       maximize the number of cluster galaxies in the WFPC2 field of view.

  question:        3
   section:        3
    line_1:        POS TARG offsets, hot pixels, and cosmic rays:        
    line_2:        For all our sets of exposures per filter, the small POS TARG offsets
    line_3:        are being done to overcome hot pixels, etc. Also, the dithering
    line_4:        using the POS TARG offsets has been done taking into account the 
    line_5:        SUM 2x2, so that the dithering is done by an integral multiple of
    line_6:        2 pixels rather than one. We have used POS TARG values of 0.4 here 
    line_7:        based upon advice from John Biretta, WFPC2 Instrument Scientist.
    line_8: 
    line_9:        Exposure times and cosmic rays:
    line_10:       After initial tests with STScI's implementation software, which gave 
    line_11:       us a better idea of actual exposure times available, we have instead 
    line_12:       specified individual exposures, all with CR-SPLIT=NO, simply shortening 
    line_13:       the first of the longest exposures in both F255W and F336W in order to 
    line_14:       allow time for the initial full guide star acquisition during the first 
    line_15:       orbit. This exposure time cut for the first exposure should not have a
    line_16:       dramatic impact on our S/N. We will shift and register the frames in 
    line_17:       order to remove cosmic rays when doing the data reduction and analysis. 
    line_18:       We will be able to use the multiple exposures in F255W and F336W to 
    line_19:       remove cosmic rays in those exposures. Hot pixels can be dealt with in 
    line_20:       all filters due to the shifts.

  question:        3
   section:        4
 
    line_1:        Summary:
    line_2:        As we mentioned earlier, in case we are photon-starved, we may be able 
    line_3:        to co-add exposures in different filters if the NO GAP/SAME ORIENT/same
    line_4:        guide stars requirements are maintained to tie together all the exposures 
    line_5:        in this program. As mentioned before, if it is necessary to break this 
    line_6:        requirement, the minimum requirement is that all exposures in each filter 
    line_7:        be done NO GAP, at the SAME ORIENT, and using the same guide stars. We 
    line_8:        also wish all exposures to be done within the period of time in which the
    line_9:        ORIENT window is available rather than having to wait another year to 
    line_10:       complete all exposures. If necessary for scheduling, the absolute ORIENT 
    line_11:       angle may be dropped or at least changed, but we request that you contact 
    line_12:       us and discuss this option with us if it becomes necessary.
    line_13:
    line_14:       Implementation Notes: 
    line_15:       After initial runs of TRANS better illustrated what should work and 
    line_16:       what would not, we decided to use individually-specified exposures with 
    line_17:       CR-SPLIT=NO and exposure times adjusted to fit as needed. The "second
    line_18:       preference" option above has been chosen also since the 1-12 NO GAP
    line_19:       option ran into trouble with the SAA and needed to be broken. Effectively,
    line_20:       this means that 1-5 and 6-12 should still each be done NO GAP, and all 
    line_21:       exposures ( 1-12 ) should still be done within 7 days. Likewise, all of
    line_22:       them ( 1-12 ) should still use the same guide stars, and be done at the 
    line_23:       SAME ORIENT angle.
