QX Pup

Update (July 7, 2015):  I-band coverage of QX Pup by AAVSO observers since 2010 clearly shows that the period given in the 4th Edition of the GCVS of 648: days is incorrect. A phase plot by Sebastián Otero of these data shows that the period of QX Pup in Ic is 551 days.

High Energy Network Overview

The AAVSO International High Energy Network came about as an evolution of the AAVSO International GRB Network. The GRB Network was established at the First High Energy Workshop for Amateur Astronomers in April, 2000. The GRB network was a great success, detecting many GRB afterglows and discovering a few on our own. The follow-up of GRB optical afterglows continues to be a major focus of the Network today.

Standardized Magnitude

The standardized magnitude for the variable is given by

Vstd = (Vins - Cins) + Cstd

where Vins is the instrumental magnitude of the variable, Cins is the instrumental value of the comparison, and Cstd is the chart magnitude for the comparison (or the equivalent for ensemble photometry).

Note that 'standardized' does NOT mean that Landolt Standards were used as comparison stars.

AAVSO Visual File Format

Version: 1.0
Release Date: January 15, 2008

This is one of two plain text (ASCII) formats that the AAVSO accepts for variable star observations. Observations in this format may be submitted using the WebObs File Upload Tool. The other format is intended for CCD, DSLR, PEP, and VISDIG (visual observations made from digital images) observers and is called the AAVSO Extended File Format.
