| Not tested as of 2015-10-22 | tested on [[NK2015_Oct23|2015-10-23]] on scan 31. The RTA failed, so the status of this Obs mode is still to be tested. |

Used on a few sources at the Jy level on [[NK2015_Oct23|2015-10-23]]. Worked fine. Should be tried on fainter sources. |

| Used on [[NK2015_Oct23|2015-10-23]] for focus on Uranus, 3C84 and Mars. If the atmosphere is stable, the method seems good, and result are reasonably reproducible (see the log for the Mars sequence for example). If the atmosphere is unstable (variable opacity), the fit looks much worse. In this case, it is on no use to add subscans for now, because the longer the observation, the more likely is the atmosphere to change opacity. The situation should improve when the opacity correction is on in the RTA. An alternative could be to fit separately consecutive triplets of -1, 0, 1 positions, and average the fits afterwards. |

Tests of the observing modes
Page last updated, HA, 2015-10-23
Status of the tests
Note on the meaning of current status:
- Not tested : not tested yet
- Tested AR : data has been taken, processing results are pending.
- Tested NOK: data taken, not working properly
- Tested OK: test data taken on at least a target and analysed. Analysis shows the Obs Mode is OK
- Fully tested OK: test data taken on many targets (bright, faint, etc..). Analysis shows the Obs Mode is OK

Pointing
nkpoint b
nkpoint b has been used from 2015-10-21 onward to point on Mars and Uranus. No problems have been noticed so far, neither on the Pako side or on the nk_rta side. No detailed analysis beyond running the RTA have been done to my knowledge. Any needed ?
- Pako script: OK
- Analysis: OK
nkpoint f
tested on 2015-10-23 on scan 31. The RTA failed, so the status of this Obs mode is still to be tested.
nkpoint l
Used on a few sources at the Jy level on 2015-10-23. Worked fine. Should be tried on fainter sources.
Focus
focustrack z
Used on 2015-10-23 for focus on Uranus, 3C84 and Mars. If the atmosphere is stable, the method seems good, and result are reasonably reproducible (see the log for the Mars sequence for example). If the atmosphere is unstable (variable opacity), the fit looks much worse. In this case, it is on no use to add subscans for now, because the longer the observation, the more likely is the atmosphere to change opacity. The situation should improve when the opacity correction is on in the RTA. An alternative could be to fit separately consecutive triplets of -1, 0, 1 positions, and average the fits afterwards.

Skydips
skydip_DIY
skydip_DIY tested on:
Pako script seems fine. FXD and NP working on analysis
- Pako script: OK
- Analysis results: pending.
skydip_tip
Tested on Oct 21 after track 19. Nothing happened, antenna did not move.
- Pako script: NOT OK
Lissajous Maps
nkliss
Tested on Jupiter + satellites on Oct 21 scan 22
Test results here
- Pako script: OK
- Analysis results: seems OK. Would be good to check again on faint source to see if the noise problems we had with NIKA are still present.
OTF Maps in Azimuth Elevation
nkotf_square
Tested on Jupiter + satellites on Oct 21 scans 24-25
Test results here
- Pako script: OK
- Analysis results: seems OK
nkotf .... azel
Tested on Jupiter + satellites on Oct 21 scans 27, 29, 30
Test results here
- scan 30 (tilted map) not reduced
- Pako script ok for angles 90 or 0, not analysed for tilted
- Analysis results: seems OK
OTF Maps in Ra - Dec
Tested on Jupiter + satellites on Oct 21 scans 31, 38
- Test only for angles 90 or 0. Other angles not tried as of 2015-10-22
Test results here for angles 0 and 90
