IMPReSS: Introduction

IMPReSS (Image PeRimeters of Sky Surveys) plots the footprints of astronomical observations within a given region of the sky and a given time. The database includes the accessible missions from HEASARC, plus IUE and HST. More missions will be added as soon as possible.

IMPReSS is divided into three working frames:

2

3

1

Frame 1 (bottom): SELECTING THE SKY REGION: Parameters: coordinates, equinox, coordinate system, region size, and start/stop dates.
Frame 2 (left): MISSION SELECTION: Select desired missions from a list of those which have observations in your region.
Frame 3 (right): OBSERVATION PLOT and DATA ACQUISITION: A color-coded plot of the selected observation footprints is produced, along with a link to the data at the appropriate data center and a list of all the observations.
