#2 on the RR Lyr stars seems incomplete in terms of the cadence. Every 10 minutes for X hours every few days over the month? Also, what filters are you looking for? We generally like to do BVI to increase the scientific value to the data set.

Thanks for your reply.
#2 Please arrange cadence of every 10 minutes for 1 hours every few days over the month.
BVI filters would be good. Please advise if there will be 3 separate FITS file for the filters.
- (3663) Dirk Terrell — Sept. 18, 2025, 2:51 p.m.
Yes, there will be separate image files for each filter.
- (50378) Eric Tang — Oct. 1, 2025, 11:22 p.m.
Sure.
Please instead share the following observation data. Much appreciated.
DSCT: DY Her
DCEP: zet Gem, T Mon, del Cep
M: T Pav, RV Cen

The Miras have long periods, 245 d and 446 d respectively. Is your project going to extend over 2 years?

Eric:
Are you now indicating that rather than the list of targets and cadence listed at the top of this proposal, you are now requesting the following targets:
DSCT: DY Her
DCEP: zet Gem, T Mon, del Cep
M: T Pav, RV Cen
Please specify the desired cadence for each, keeping in mind that AAVSONet is a shared resource. How long is your project? One semester? IOW, when do you actually need all the data? The 2 Miras have a long period that would require a year or more of bi-weekly images? The DSCT target could probably be completed with a 4 hour time series x 2 days? The DCEP targets would take one set of images nightly for about 2 months. Is this consistent with what you need to do? Do you need to analyze the images OR do you only need to analyze the periods from data already in the AAVSO database?
