GBT 6cm Observations of "The Brick"
6cm observations of G0.253+0.016, AKA "The Brick" or "The Lima Bean" taken as part of project GBT12B/221.
Three spectral line cubes are include: H2CO at 4.829 GHz, H213CO at
4.3888 GHz, and H110a at 4.874157 GHz. Other RRLs were detected, but not carefully reduced.
Baseline subtraction was performed by interpolating across the line-containing region; there is therefore some uncertainty in the true baseline (continuum) level.
