Request access
You can access TMSS with a LOFAR account that is also used for NorthStar and the previous specification system, MoM:
- If you had a LOFAR account before, but forgot your password, please request a new password instead of making a new account.
If you don't have a LOFAR account, you can create a new account.
To be authorized for TMSS, you also need to have the right authentication method. Please check first that you have the right password to your account by login in to the proposal tool Northstar .
If you can access that, but not TMSS, then please send a request to the SDC helpdesk stating:
"I have created an account with user name <USERNAME>. Can you grant me access on this account to TMSS?"
You may need to reset your password for your LOFAR account to work.

Default observing strategies
| Observing mode | Observing mode explanation | Strategy | Strategy type | Number of station beams / target fields (excl. calibrator) | Antenna set | Filter | Frequency range/ subband list Subband List | Default station list | Default settings | Free settings | Recommended settings |
|---|---|---|---|---|---|---|---|---|---|---|---|
| LBA Imaging | Imaging with the Low Band Antennas (LBA) is performed with one or more target beams and a calibrator beam in parallel. Scheduling units / scheduling blocks are created with one observation per scheduling unit and these are scheduled independently. | LoLLs (default) | Default imaging strategy for ??-?? MHz. Observations can be requested in co-observing mode where high level dataproducts are made available to the user for 1-2 target fields per observation and the other targets are used towards the LoLSS survey. | 3 | LBA_Sparse_Even | 30-90 MHz | NL. Mandatory RS210, RS310, (RS508 or RS509) | Demix | Duration of 3x1 hr or 1x8 hr | ||
| LoDess (default) | Default imaging strategy for 10-30 MHz for the LoDeSS survey for 5 independent target fields. | 5 | LBA_Sparse_Even | 10-90 MHz | NL. Mandatory RS210, RS310, (RS508 or RS509) | Duration of 5 hours | |||||
| HBA imaging | Imaging with the High Band Antennas (HBA) is performed with one or more target beams within the tile beam. Calibrator observations will be scheduled before and after the target observation, but one of those can be omitted. | LoTSS | Default imaging strategy for 120-168 MHz  . Observation can be requested in co-observing mode where high level dataproducts are made available to the user for 1 target field per observation and the other target field is used towards the LoTSS survey. | 2 | HBA_Dual_inner | 110-190 MHz | LoTSS subband list. Range . Subbands that have high RFI are replaced by higher frequencies for spectral line studies. | All stations, including International stations, | Recording at 64 ch/subband, 1 second. Preprocessing output at 16 ch/subband, 1 second time resolution | Duration of 8 hrs or 2x4 hrs, depending on elevation. | |
| Single beam | Similar to LoTSS, but with a single target beam | 1 | HBA_Dual_inner | 110-190 MHz | LoTSS subband list. Range . Subbands that have high RFI are replaced by higher frequencies for spectral line studies. | NL | |||||
| Fast response | Similar to LoTSS, but with a single target beam and omitting the first calibrator observation such that the target observations is performed as soon as possible. | 1 | HBA_Dual_inner | 110-190 MHz | LoTSS subband list. Range . Subbands that have high RFI are replaced by higher frequencies for spectral line studies. | NL | |||||
| Beamformed complex voltage / baseband | This beamformed data mode provides the highest time resolution data. Currently it is offered on a single pointing with several default observing and processing setups. | Pulsar Timing | Default beamformed strategy that delivers folded pulsar profiles for known pulsars at 110-188 MHz at a frequency resolution of 195 kHz. | 1 SAP, 1 TAB | HBA_Dual | 110-190 MHz | 51-450 | Core | |||
| Pulsar Timing Scintillation | Default beamformed strategy that delivers folded pulsar profiles for known pulsars at 110-188 MHz at a higher frequency resolution than the regular pulsar timing observations. | 1 SAP, 1 TAB | HBA_Dual | 110-190 MHz | 51-450 | Core | |||||
| Compressed data (8-bit) | Default beamformed strategy that delivers raw data compressed to 8-bit for flexibility in the analysis. This can be used for pulsar and FRB searches or scintillometry studies. | 1 SAP, 1 TAB | HBA_Dual | 110-190 MHz | 51-450 | Core | |||||
| Fast Radio Burst | Default beamformed strategy that delivers a dynamic spectrum at a specified dispersion measure using digifil. This is used for known fast radio bursts. It can in addition deliver the raw data compressed to 8-bit. | 1 SAP, 1 TAB | HBA_Dual | 110-190 MHz | 51-450 | Core |
