CFHT Update

For Semester 2001B

This an update concerning the current status of instruments as well as other information regarding submission of proposals.


Semester 2001B Proposals:

Deadline is March 21, 2001 - 24:00 UTC

All proposals from Canada and France for Semester 2001B must use the electronic proposal system operated by the Canadian Astronomy Data Centre. The Phase One Observing Proposal SYstem (POOPSY) is an electronic submission system which uses a standard Web browser but is based on LaTeX, a familiar formatting language. Consult the Users Guide for more information.

Some important notes:


Instrument Availability

CFH12K   (Contact Jean-Charles Cuillandre (jcc@cfht.hawaii.edu) for information)

CFH12K is the CFHT prime focus wide field visible camera (FOV=28'x42'). It is a 12,288 by 8,192 pixel CCD mosaic made of 6x2 CCDs (2k x 4k) with a pixel scale of 0.2 arcsec. The back-side illuminated CCDs provide high sensitivity, in particular in the B band. The filters available are: B, V, R, I, Z', Halpha, HalphaOFF, TiO, CN.

Consult the updated CFH12K Web pages for detailed information on the characteristics and performances of the camera.


CFHTIR    (Contact Thierry Forveille (forveille@cfht.hawaii.edu) for more information)

CFHT-IR is a new general purpose 1024 x 1024 near-infrared camera designed for direct imaging at the F/8 (and for imaging/spectrocopy on OSIS).
Cassegrain focus. Commissioned at the end of 2000 and already used for a scientific run in January 2001, it is expected to be fully operational in the F/8 direct-imaging mode for the semester 2001B.


GECKO/CAFE   (Contact Nadine Manset (manset@cfht.hawaii.edu) for more information)

GECKO will be run with a coude mirror trains in the UV (below 4000A or so), and through CAFE, the CAssegrain Fiber Environment, for other wavelengths. CAFE has been successfully installed and used in July 2000B, providing more flexibility in scheduling Gecko runs.

There is no shortage of potential CCDs available for Gecko in 2001B. Beside Loral3 which is a thick 2K x 2K device with 15 micron pixels, EEV1 is available. EEV1 is a 2k x 4.5k device with 13.5 micron pixels. A short summary of device characteristics is:

Loral3: Low Q.E. in blue but the only device which will not have fringing in the red. Read noise around 9 electrons

MOS   and OSIS-V    (Contact Eugene Magnier (magnier@cfht.hawaii.edu)for information)

MOS is a multi-object spectrograph covering a 10x10 arcmin field which can also be used in direct imaging and in Fabry-Perot mode.

OSIS-V is a visible spectrograph covering a 3.6x 3.6 arcmin field.
OSIS fast guiding is working reliably. Images with  0.39" FWHM using the fast guiding have been obtained with OSIS-V.

With the fatal failure of STIS2, EEV1 is the detector of choice for both MOS and OSIS. If the fringing in the red is a problem for the observations, the old Loral3 could still be used. The latest news on MOS and OSIS can be found here.

A summary of the grisms and filters available for MOS and OSIS is available.

The ARGUS mode of MOS is no longer offered (see OASIS).


OASIS   (Contact Pierre Martin (martin@cfht.hawaii.edu) for more information)

OASIS is an integral field spectrograph which can be used in conjunction with the Adaptive Optics Bonnette, to give low to medium resolution spectroscopy with  spatial sampling as high as 0.04". OASIS can also be used directly at the F/8 Cassegrain focus.

EEV1and Loral3 are the two detectors available for OASIS. Check the  latest news on OASIS...

Note that most of the programs which could have been performed with MOS-ARGUS can use OASIS instead.


OSIS-IR (Contact Eugene Magnier (magnier@cfht.hawaii.edu) for information)


OSIS-IR is proposed for the second half of 2001B on a shared risk basis. CFHTIR will be the detector used in this mode. As OSIS-IR won't be tested on the sky before May 2001 (if not later), no on-sky test data are available for this instrument yet... You can look at the OSIS information for a reminder on the previous OSIS-IR configuration (with the redeye detector).


PUEO  (Contact Olivier Lai (lai@cfht.hawaii.edu) for information)

PUEO is the CFHT Adaptive Optics Bonnette. For observations in infra-red, KIR is the detector to be used. Detailed information on  performance and results are available on the KIR and the PUEO Web pages

For observations in the visible, FOCAM and a standard CCD are available. There are two modes available for FOCAM with AOB with and without a focal enlarger. Pixel scales are 0.022 or 0.044 arcsec in the visible for Loral 3, with and without the focal enlarger respectively.

NOTE: The GRiF K-band integral field spectrograph will be available on a shared risk basis. What modes will be available will depend on the integration schedule. Currently, KIR can be operated with the Fabry-Perot (R=1800).
The next steps will be the integration of the grism in the filter wheel and the focal plane wheel, which will allow long slit specroscopy with a resolution of R~500. If these two modes are integrated together, the integral field spectrograph will be operationnal. Please check the PUEO web page for the latest news on these developments.
