Proposal Type: General Category: Observation Category: Total Time Requested: Minimum Useful Time: Prop osal Title: ABSTRACT:
We propose re-observing for an hour of lost time on pro ject P2676, observing pulsar B1937+21 with PUPPI at L-band. The error occurred due to an unforeseeable equipment failure with two aspects. The first occurred during an in-person observing session when the entire system of PUPPI' s GPU nodes became non-responsive for a half hour during our scheduled time. Later, upon first analyzing the data, it quickly became clear that even the good data from the second half hour of the observing session was problematic. After correspondence with colleagues, we discovered that the error was in the instrument' s electronics, and that it had been present before our observation. In light of these two independent instrumental problems which had occurred during our first hour of observing time (followed by successful remote follow-up observations), we request an additional hour on B1937+21 during the late afternoon/early evening hours. This can easily be done remotely.
