The ASCA AO-4 NRA is released
Dear ASCA Proposers:
The fourth ASCA NRA (AO-4) has just been released. It will follow this
15 June, 1995 NRA Release
15 September, 1995 Stage-1 Proposals due
early December, 1995 Stage-1 selections announced
mid December, 1995 AO-4 observations begin
1 January, 1996 Stage-2 proposals due

As for AO-3, you can obtain a hardcopy of the NRA appendices by emailing
your postal address to:
You can also obtain the appendices via anonymous FTP at
in the directory
and its subdirectories, or via WWW at:
The rest of this message is intended to provide a concise summary of the
important changes in the ASCA program and instrumentation since AO-3.
These changes are:
ASCA PROPOSALS ARE NOW IN TWO STAGES
To save time and resources, ASCA proposals are now in two stages, like
XTE. Stage-1 is for the science part of the proposal only. Stage-2,
which takes place after the merging of the US and Japanese programs, is
for the budget only. Details in Appendix C of the NRA.
RPS HAS TWO NEW, EASIER-TO-USE INTERFACES
The Remote Proposal Submission software (RPS) has two interfaces which
make electronic submission easier: one using email, the other using
Mosaic and Netscape (but only for workstations). Details in Appendix D
of the NRA.
SIS 4-CCD MODE IS NOW UNUSABLE
Due to various manifestations of radiation damage, SIS 4-CCD mode is
effectively unusable. Observations which would have been done in 4-CCD
mode earlier in the mission can still be performed using 2-CCD mode with
longer exposures. Proposals specifying 4-CCD mode will not be accepted
on the US side unless the proposers can demonstrate an in-depth
knowledge of the instrument and the special need for 4-CCD mode.
Details in Appendix E of the NRA.
