The Prosper Projekt

Required format of observations

The format of observations (even individual points are useful!) should be the following (very similar to the MEDUZA format):

Position:	1	11	25	35	55	65
Field:	name of the star	julian date	magnitude	date (UT)	observer’s abbreviation	estimate(s)
Example:	QR And	2451139.256	11.28	1998-11-21.756	XY	E4V2F

The observer's abbreviations are the same for PROSPER and MEDUZA group.

Some remarks to the charts

Each star has two independent charts. The first chart is intended particularly to visual observers. In the upper right corner of each view port, there is shown the level of the chart by Roman numerals. In the lower left corner there is an explanation of used magnitudes and orientation. Lower parts of the view ports contain also the information about scale. Stellar magnitudes are in visual passband and are in decimagnitudes. The variable is denoted by two lines in the last view port. Lowercase letters denote preliminary comparison stars, for these stars, V band magnitudes are given on the chart.

The second chart is intended to observers equipped with CCDs. The upper view port of the chart contains close vicinity of the variable star, lower left corner contains explanation of used magnitudes and orientation. Numbers near the stars are brightness’ in decimagnitudes. Box in the view port corresponds to the image in the bottom of the chart. The variable star is denoted by two lines both in the finding chart and the image. Arabic numerals give preliminary comparison star for which V and B-V were computed.

Useful tool for CCD observers could be "reference stars". They are one or more very bright stars, mostly seen by naked eye, which can be used for the setup of the telescope.

Stellar magnitudes were taken from Tycho-2 catalogue and recalculated to Johnson V using formulae supplied with the catalogue.

Charts for visual observers are shipped together with this issue of Perseus. CCD observers can find them on the Internet in TIFF and PS formats or they will be send to them upon request.
