Cycle 12 Phase II Proposals

-Inge Heyer and James Rhoads

The Cycle 12 Phase II deadline is May 16, 2003. Documents to 
help observers in the preparation of the Phase II proposals
are available on our website.

One notable change for Cycle 12 is the introduction of the
APT proposal preparation tool for Phase II, which will be
the default tool as of Cycle 12. Training videos, manuals,
and other information regarding APT are available at
http://www.stsci.edu/hst/proposing/apt.

WFPC2 Filter Wavelengths in the Archive

-Anton Koekemoer and Gabriel Brammer

The HST Archive / CDBS catalog contains a number of different 
quantities that characterize the properties of each filter in 
the WFPC2 filter set. These quantities include the "Central 
Wavelength", which appears as a default output column in 
archive searches, as well as the "Pivot Wavelength" and other 
related quantities that are used to calculate photometric 
keywords such as PHOTFLAM, which can be used to define the 
zeropoints for WFPC2 photometry. The "Central Wavelength" 
values have been unchanged since the launch of WFPC2. They are 
not used to calculate any other quantities, yet have always 
appeared as a default output column in archive searches. On 
the other hand, quantities such as the Pivot Wavelength are 
better defined and are also regularly updated whenever there 
are changes to the system throughput tables in Synphot. There
have also been a few discrepancies between Central Wavelength 
and other, more up-to-date quantities, which have on occasion 
led to confusion. Therefore, the WFPC2 group, in conjunction 
with personnel in charge of CDBS, have chosen to replace the 
use of "Central Wavelength" with the use of "Pivot Wavelength".
The only effect that this will have is that, when archive 
searches are performed, the wavelengths listed for filters will 
now reflect the Pivot Wavelength. No other quantities are 
affected by this change; in particular, photometric keywords 
within the WFPC2 dataset headers will remain unchanged, since 
they are already consistent with the Pivot Wavelength and other 
regularly updated filter quantities. More details on this, 
including a table comparing the old Central Wavelength with the 
up-to-date Pivot Wavelength values for each filter, are 
available at the WFPC2 Website.

WFPC2 Cycle 9 Closure Report

-A. M. Koekemoer, S. Baggett, S. Casertano, S. Gonzaga, I. Heyer,
and the WFPC2 Group

This report describes in detail the WFPC2 observations used 
to maintain and improve the quality of WFPC2 calibrations 
during Cycle 9, and their status at completion of the Cycle.
