Derek, I'm having trouble interpreting this. I don't think that you observed it for 2417 seconds so that must be frames, right? So, what is the frame rate? Or (what I really want), what is the time interval between blips? Randy Define "blips".. If you mean each point on the lightcurve, yes it is frames, 29.97 fps, and ~0.033s per frame / point on the light curve.. If you mean the interval of the "heartbeat"..... Starting with the full lightcurve on the web page, going left to right, the first peak mag of NOSS 3-3 C, where it is above the 4,000 level at around frame 601.. that occurred at a UT time of 3h 31m 52.8003s +/- 0.008s.. i.e. the center of an interlaced frame.. Moving to the right, here are the times of the next three peak points.. 3 31 54.6357 3 31 56.9045 3 31 59.1067 >From frame 241 to frame 1981 (based on the split light curve - "First Part" and "Second Part" - and using the rough frame numbers listed across the bottom of the lightcurves, you have the following first and last peak point times.. Point #239 3h 31m 40.2209s Point # 1990 3h 32m 36.6469s There are 29 "events" including those at the start and finish and a duration for 56.4260s / 28 = a 2.015s period. -----Original Message----- From: seesat-l-bounces+breit_ideas=poyntsource.com@satobs.org [mailto:seesat-l-bounces+breit_ideas=poyntsource.com@satobs.org] On Behalf Of Randy John Sent: Monday, October 01, 2012 5:26 PM To: Seesat List; videoastro@yahoogroups.com Subject: RE: Noss 3-3 C lightcurve posted Derek, I'm having trouble interpreting this.
