ATEL within 24 hours of each observing night. This ATEL should list all new classifications that were made during the night.
Each ATEL can follow this generic outline, filling in the table of classifications as appropriate. Smartt et al. 2015, A&A, 579, 40 with fuller details on the survey.
For "Disc. source" use one of LSQ, SkyMapper, PS1, ATLAS, ASASSN, OGLE, etc a different survey, or TNS, as appropriate.
Note that in the example below, the table should be formatted with spaces rather than tabs. The <pre> tag will ensure that the formatting of the table is preserved, but it may not show up correctly when you go to "Preview ATEL". It will, however, appear fine when the ATEL is actually published.
Don't forget to replace the OBS MONTH and OBS DAY values in the ATel example below.
And don't forget the title should be from April 15th 2017 onwards
ePESSTO spectroscopic classification of optical transients
–10 to –8
–7 to –4
–3 to +3 (or just "at max” which we will take to mean these days)
+4 to +7
+8 to +10
+11 to +20
> +20 (or “several weeks after max”)
These phases tie into the numbers we will be using in the ESO catalogue.
1. We should report info on any object for which we have a spectrum, even if its stellar, AGN, or host galaxy dominated. Of course, info should also be reported and preserved in the Marshall. We should do this for every object we actually take a spectrum of. And these spectra should go to WISEREP, and Phase3.
2. Even if the classification is ambiguous or not possible, the spectrum should be reported in the ATel. A simple description of the first spectrum should be provided. For example, blue featureless continuum objects are common and these should be reported as such. Additional information can be provided in the next ATel when a higher S/N spectrum is taken. But as a rule, always record the first spectrum taken and a qualitative description if classification is not possible.
3. We should NOT report info in ATELs that private objects which were not in the public domain are invisible (if we don't go on to take a spectrum). Remember, such targets have never been publicly announced, therefore we should not make statements of the non-existence of unannounced objects. But it is essential that the observers/reducers record the info in the Marshall to feedback to LSQ team.
4. If objects have been publicly announced (e.g. MASTER, PSN, CSS, PS1) and we then find they are not visible, then we should indeed report this info in the ATEL. This is useful info to propagate to the community.
1. PESSTO observers at the telescope for that night,
2. PESSTO data reducers for that night
3. Target and alert team members on duty - those people who have been through the lists to help select the classification targets. You can see them on the marshall or on the this page of the duty roster.
These first two lists can be rotated around at the discretion of the observers and data reducers. Then the following :
4. The PESSTO builders list (For all ATels from Year 4) PESSTO_Policies#PESSTO_builders_list. : C. Inserra (Southampton), E. Kankare (QUB), K. Maguire (QUB), S. J. Smartt (QUB), K. W. Smith (QUB), M. Sullivan (Southampton), S. Valenti (UC Davis), O. Yaron (Weizmann), D. Young (QUB)
During April - May 2017, the builders list should remain as above. The ePESSTO Builders list will be constructed during June-July 2017.
5. I. Manulis (Weizmann) will be the WISeREP person on duty and will do the data upload to WISeREP, and should be added to the ATel author list.
6. Feeder survey lists
For (6), if a target from a given feeder survey is used (i.e. is listed under "Disc. source" in the ATEL table) then the following people and acknowledgements should be added to the ATEL:
Pan-STARRS: Add this to the ATel text "Targets were supplied by Pan-STARRS Survey for Transients (see Chambers et al. 2016, arXiv:1612.05560, and http://pswww.ifa.hawaii.edu) " and add the authors : S. J. Smartt, K. W. Smith, D. Wright (QUB), K. C. Chambers, H. Flewelling, M. Huber, T. Lowe. E. Magnier, A. Schulz, C. Waters, R. J. Wainscoat, M. Wilman (IfA, Univ. Hawaii).
ATLAS : add this to the ATel text : "Targets were supplied by the ATLAS survey, see Tonry et al. (2011, PASP, 123, 58) and
Tonry et al. (ATel #8680)". And add the co-authors J. Tonry, B. Stalder, L. Denneau., A. Heinze, H. Weiland (IfA, Univ. of Hawaii),
A. Rest (STScI), K.W. Smith (QUB), S. J. Smartt (QUB)
SkyMapper: A. Moller, B. Tucker, B. Zhang, B. Schmidt (Australian National University) and cite Scalzo et al. ATel #5480.
The HITS survey with DECam (Chilean collaboration) : F. Forster, J.C. Maureira, J. San Martin, G. Cabrera, Eduardo Vera (CMM), Mario Hamuy, S. Gonzalez-Gaitan, Lluis Galbany, Th. de Jaeger (DAS), Joseph Anderson (ESO), Giuliano Pignata (UNAB), and R. Chris Smith (CTIO)
OGLE : L. Wyrzykowski,(Warsaw Observatory, Poland) and cite "OGLE-IV Real-time Transient Search (Wyrzykowski et al., 2014 arxiv:1409.1095; http://ogle.astrouw.edu.pl/)"
La Silla Quest (LSQ): C. Baltay, N. Ellman, E. Hadjiyska, R. McKinnon, D. Rabinowitz, S. Rostami (Yale University), U. Feindt, M. Kowalski (Universitat Bonn), P. Nugent (LBL Berkeley) and cite Baltay et al. 2013, PASP, 125, 683
7. Acknowledging Public Surveys
The following surveys release their data publicly and they are ingested into the marshal. Co-authorship of the ATels is not required, but acknowledgement is, and the appropriate text and citations are :
ASASSN: add this. Targets are are from the All Sky Automated Survey for SuperNovae ASAS-SN (see Shappee et al. 2014, ApJ, 788, 48 and http://www.astronomy.ohio-state.edu/~assassin/index.shtml)
GAIA : add this to ATel text : We acknowledge ESA Gaia, DPAC and the Photometric Science Alerts Team (http://gsaweb.ast.cam.ac.uk/alerts) or
"targets are from the ESA Gaia Photometric Science Alerts Team and DPAC (http://gsaweb.ast.cam.ac.uk/alerts)"
Use either, depending on how you phrase the ATel.
CRTS : if targets come from CSS/MSS/SSS, which are surveys of the Catalina Real-time Transient Survey. Then add "from the Catalina Real-time Transient Survey (CRTS; Drake et al. 2009, ApJ, 696, 870 ; http://crts.caltech.edu/)."
DES : Dark Energy Survey Supernova Program (DES-SN) publishes its brighter (r ≲ 20) transient candidates. If these are classified then add "targets supplied by the Dark Energy Survey Supernova Program (see Kessler et al. 2015, AJ, 150, 172 and https://portal.nersc.gov/des-sn/)
MASTER : "targets supplied by MASTER (see http://observ.pereplet.ru/ ; Lipunov et al. 2004, AN, 325, 580)
Virtually all amateurs now submit their targets to the IAU Transient Name Server (i.e. the object has an AT2016xxx name). You should add "targets were taken from the IAU TNS list (see https://wis-tns.weizmann.ac.il/) ". We let the TNS deal with the discovery and classification certificates.
No co-authorship is required, now that we have this stable, and IAU recognised, platform for discovery attribution.
Historical Note : up to the end of PS1 operations (mid-2014, this was the author list for PS1 targets provided to PESSTO). However this has been replaced by the new acknowledgement above for any Pan-STARRS targets from end of 2014/beginning of 2015 onwards.
