IRAM30MLOG - IRAM 30-m Single-Dish Telescope Observation Log
IRAM operates two observatories at millimeter wavelengths which are open to the international astronomical community: the 30-m single-dish telescope on Pico Veleta (2850 m), Spain, and the six-antenna interferometer on the Plateau de Bure (2550 m) in France. Both sites are at high altitude to reduce the absorption by water vapor. The observatories are supported by the IRAM offices and laboratories in Granada and Grenoble.
The observation log included here concerns the 30-m single-dish telescope, and summarizes the observations made there since September 30, 2009.
The observation log for the the six-antenna interferometer on the Plateau de Bure in France is also available as the HEASARC database table IRAMPDBLOG, and the observation log for NOEMA (the NOrthern Extended Millimeter Array), the successor to the Plateau de Bure observatory, is available as the HEASARC database table IRAMNOELOG.

The source designation as given in the observing program.
The Right Ascension of the observed source in the selected equinox. This was given in J2000 coordinates and to a precision of 0.01 seconds of time in the CDS table upon which this Browse table is based.
The Declination of the observed source in the selected equinox. This was given in J2000 coordinates and to a precision of 0.1 arcseconds in the CDS table upon which this Browse table is based.
The Galactic Longitude of the observed source.
The Galactic Latitude of the observed source.
The start time and date of the observation in UTC.
The end time and date of the observation in UTC.
The scan number of the observation on the day corresponding to the start time. The internal IRAM identifier of the observation ncsID is of the form Date.scan, e.g., the observation with scan number 2 on 2009 October 01 has ncsID = 2009-10-01.0002.
The observation mode used. The various observation modes are as follows:
* VLBI * onOff (taking data on and off source in quick succession) * onTheFlyMap * pointing * track * calibrate * focus * tip (a calibration to measure the opacity)
The identification code of the IRAM 30-m single-dish telescope program.
The zenith optical depth tau at a frequency of 225 GHz from the tipping taumeter.
The short name of the receiver (band) used for the observation, e.g., E090 for the EMIR band E0 at 90 GHz, HERA 1, MAMBO2, etc.
The name of the spectral line observed, e.g., '12CO(1-0)', etc. If the observation was not of a spectral line, this field contains the observing frequency, in MHz, e.g., '212500'.
The observing frequency used, in GHz.
The name of the Principal Investigator under whose program the observation was carried out.
