Observing Time Estimator Version 2

History

The Time Estimator in its version 2 offers some new possibilities with respect to its previous release. All new features are described in detail in the HELP page but we give here a complete list of the new options appearing in this latest version:

Version 2.7 (RM & HW - Feb 2007)

• HERA1 and HERA2 assumed to be tuned to the same frequency except above 241 GHz where only HERA1 is available

Version 2.6 (RM - Feb 2006)

• switched defaults to summer conditions, used 60s on-time as default for the bolometer

• 2nd polarization included for Hera.

• Extended frequency range for B100 included (72GHz upwards).

• New autocorelator "Wilma" included (fix freq. resolution 2MHz).

• Inclued use of the 4MHz filterbanks for OTF mapping.

• 117 channel bolometer included in Bolometer calculator

• 4MHz filterbanks included in Hera calculator

• Updated sensitivity for MAMBO and MAMBO-2

• Autocorrelator (VESPA) for HERA observations

• Time estimations for HERA observations

Version 2.3 (PHB - February 2001)

• sensitivity of the bolometer updated for summer conditions : NEFD = 45 mJy.sqrt(s)/beam

Version 2.2 (PHB - August 2000)

• 4 MHz Filter Bank added

Version 2.1 (PHB - February 2000)

• r.m.s are now given in mK,

• The receivers temperature are interpolated from a given set of Trec at specific frequencies, with a Lagrange polynom.

Version 2.0 (DT- July 1999)

• Time estimates for future receivers C and D using the most recent receiver performances available. This extend the observing frequency range to 293 GHz,

• The tuning time is now constant for up to 4 receivers: 20 minutes,

• The r.m.s. is now estimated for every receiver requested in the calculation,

• Time estimates for continuum observations with the MPIfR bolometer,

• Time estimates now account for receivers simultaneously tuned at the same frequency. It informs of the possible gain in time resulting from this average,

• Some tricks to simulate spatial smooth of maps,

• All formulas and methods used in the Time Estimator are now gathered in a complete report ,
