Reports

Guidelines on reports
With the advent of large-scale surveys and widely available CCD photometers on large numbers of small telescopes around the world, the number of new variable stars being discovered is increasing fast. It is no longer possible, or desirable, to publish an issue of IBVS solely on the discovery of a new variable, unless the star is of special astrophysical interest and significant observation and analysis are included in the paper submitted to IBVS.

 If the information to be published is that a new variable has been found, but without substantial observations and analysis, then this will be a "Report on New Discoveries" note in the shortest format, where a finding chart, type and light curve should be provided. Photometry of known variables without discussion, or with short remarks (that may include times of minima) are directed to "New Observations of Variables". For discovery reports we require well covered light curves, and determination of main parameters like type of variability, period, etc. Visual observations, or those without filter are not accepted. Exceptions are made only in scientifically important cases, where no further observations are possible. We ask you to specify which databases/catalogs were checked to ensure that the star has not been reported before.

 Reports appear one-by-one, published electronically immediately, and are collected in special issues that are closed down whenever the numbering of the regular papers reaches these special issues. The running “Reports on New Discoveries” issue is always the nearest hundredth issue (e.g. issue 6200), and the running "New Observations of Variables" issue is the one before it (e.g. 6199).

 Note that Reports can only be published if observational data are submitted with the report.

 

Content requirements

Discovery notes should contain the following information, in a plain ASCII text file:

- Name(s) and affiliation(s) of the observer(s) (one line per person);
- Data on the newly discovered variable: coordinates, type of variability, period, epoch (for eclipsing binaries that of the primary minimum); magnitude and photometric band;
- Cross-identifications.

Finding chart, light curve should be attached as images. Mark scale and directions, and identify objects on the finding chart, and include object identification to the light-curve plot too. We ask the authors to submit their data files as well, in a plain ASCII text file. Data files should contain object name, observer, information on the telescope/detector/filter, columns should have proper headings.

New observation reports should contain the following information, in a plain ASCII text file:

- Name(s) and affiliation(s) of the observer(s) (one line per person);
- Name of the variable;
- Brief remarks.

Include object identification to the light-curve plot. Data files should be submitted in a plain ASCII text file, and should contain object name, observer, information on the telescope/detector/filter, proper headings are needed for the columns.
