Useful data: 15191 / 23390 sec = 65%. meaning we have a lot of problems in our data: 2 scans have wrong RA offsets and cannot be coadded; many scans have high noise in half of the channels, reason unknown; three scans have asymmetric noise in the phase differences; several have strong acceleration effects. Scans 34-40 on Dec 18-19 are not useful, their total integration time adds to 2806 sec = 18% of our data. Note that the total overhead factor is apparently 12.8h/15191sec = 3.0. I would have expected 2.0.

Dear Chris, In reply to your request for DDT observing time where you propose to add two new z>6 quasars to your on-going programme (175_05), I am happy to let you know that I accept your request as follows: - For the two new quasars (J2315 and J0353), 3 hours per source in A - For improving the s/n ratio of the two other source, I would recommend that you concentrate on J1335 J1335 (2 hours in A.) I would suggest to put J1602 for 2 hours in B. Please contact Clemens Thum for any further details concerning this request. With best regards, Pierre

Re: Addendum to 175_05 MAMBO: Discretionary time at the 30m/MAMBO
to add two interesting new z=6.1 QSOs to the current program
and for extra time on two possible new mambo detections
cc: leon@iram.es
To the Director's office,
We have an on-going, approved program at the 30m (175_05) with MAMBO
to image z = 6 SDSS QSOs at 250 GHz, in parallel with a program
that is currently underway with the VLA to observe these sources at
1.4 GHz. These programs continue our successful study of the dust,
that is currently underway with the VLA to observe these sources at
1.4 GHz. These programs continue our successful study of the dust,
molecular gas, and star formation properties of the host galaxies of
the highest redshift QSOs, approaching cosmic reionization,
corresponding to the epoch of first galaxy and SMBH formation.
We are requesting to extend this program this winter for two reasons:
1. Over the past few weeks the SDSS group has discovered two new QSOs,
listed below, both at z=6.1. These two sources are particularly
interesting in that they are a magnitude fainter (in the optical) than
previous z=6 QSOs, and hence begin to broaden the sample in terms of
their optical properties. We would like to add these sources to
175_05 this winter, asking for the same 3 hours per source (total new
request = 6 hours with MAMBO) to maintain a uniform sensitivity for
the full sample. The new sources at z=6.1 are:
SDSS J2315-0023 23:15:46.567 -00:23:58.07 z_AB=20.82
SDSS J0353+0104 03:53:49.718 +01:04:04.44 z_AB=20.53
2. In our original sample of 4 QSOs this winter, we have one firm
detection (0927+2201 at 5sigma), plus two likely detections (1335+3533
and ?? at 2.5sigma). We would like to confirm, or refute, the two
lower SNR detections. Each new mm source at z=6 becomes a critical
target for follow-up molecular line studies, thereby extending mm
astronomy into cosmic reionization and the first generation of
galaxies. Hence, confirming possible detections is crucial. We ask for
an additional 3 hours per source.
Our total DD request is then 12 hours.
Respectfully yours,
Chris Carilli
