Introduction

We updated the entries with the latest information of sky coordinate, color, rotational velocity, spectral type, period, amplitude and binarity. The majority of our sample are well characterized in terms of typical period range (0.02 ~ 0.25 days), pulsation amplitudes (less then 0.5 mag) and spectral types (A ~ F type).

Given this list of delta Scuti stars, we examined relations between their physical properties (i.e., periods, amplitudes, spectral types and rotational velocities) for field stars and cluster members, and confirmed that the correlations of properties are not significantly different from those reported in Rodriguez's works.

All the delta Scuti stars are cross-matched with several X-ray and UV catalogs, resulting in 27 X-ray and 41 UV-only counterparts. These counterparts are interesting targets for further study because of their rarity and uniqueness in showing delta Scuti-type variability and X-ray/UV emission at the same time. The complied catalog can be accessed in this web site.

TODO: The following is a TODO list for imporving our delta Scuti catalog.

1. Add a Pingulski's catalog
2. Add a published list of LMC or SMC delta Scuti stars
