Discussion

Haven't yet looked at the correlated data.

V-FASTR Data

From Kiri:

This one was broken into 3 jobs:

bb325dc_1

Source Name: J1936+3642 Source RA: 5.133 Source Dec: 0.641 ** 12 rejected detections

bb325dc_2

Source Name: GCN614415 Source RA: 5.081 Source Dec: 0.630 ** 20 rejected detections

bb325dc_3

Source Name: B2020+28 Source RA: 5.335 Source Dec: 0.505 ** 5 detections marked as "pulsar", all with DM = 24.19 ** 2 rejected detections

Is this helpful?

Correlated Data

On 13 Oct made the following request to change the phase center:
Hi,

There is an updated position for this GRB.

Can you please correlate the BB325BC scans of GCN614415

With the following  ra/dec?

RA = 19:24:22.392 dec = +36:05:42.26 (J2000)
